Electronic Waste Recycling Act

The Electronic Waste Recycling Act (“Act”) became law in California on January 1, 2005. The primary objective of this law is to initiate a recycling program for computer products containing chemicals deemed hazardous to the environment. To fund this program, California requires retailers and e-tailers to collect, on the state’s behalf, a fee for each product covered by this law. The consumer pays the fee at the time of purchase of the covered product. This fee will be remitted directly to the state by and only applies to orders shipped within California.

The types of products that we are required to collect this recycling fee include cathode ray tubes, cathode ray tube devices, flat panel screens, and other similar video display devices.

The actual amount of the recycling fee will vary, based on the screen size of the product when measured diagonally, as follows:

• Greater than 4″ and less than 15″: $4.00
• Greater than or equal to 15″ and less than 35″: $5.00
• Greater than or equal to 35″: $6.00

Product Testing

NonprofitComputers, like many other retailers, ships items in the condition they were received from the original manufacturer and/or distributor, vendor, supplier. NonprofitComputers does not conduct product testing before shipping any merchandise.

Return Policy

PLEASE READ THIS ENTIRE POLICY

Computer hardware: Desktop and laptop computers unless otherwise indicated may be returned within 30 days from the original invoice date for a refund as long as you only purchased one computer. There are no returns on any order over one unit (Q=1). A return merchandise authorization number (RMA) is required for all returns. Most products are shipped with a 30-day refund period unless otherwise noted in the product listing. No refunds after 30 days. Customers must inform NonprofitComputers of any order discrepancy within 7 days from the invoice date so that we may investigate and resolve the situation accordingly.

IMPORTANT INFORMATION ABOUT COMPUTER HARDWARE RETURNS:
1. You may only return a computer if you purchased one computer (quantity=1). We are a B2B seller (nonprofits are not “consumers”). Every computer we ship includes a 5-year warranty and support. Orders with any quantities of two or more computers are not returnable. If an order contains two or more computers, no part of the order may be returned.

2. You may only submit one computer return every 30 days. This is to prevent an abuse of our policies, for example a customer ordering “one” unit 25 times in the same day hoping to have a 30-day return policy for all of them, thus attempting to not adhere to the Q=one policy, or any other abuse of our return policy.

3. NonprofitComputers reserves the right to refuse any return and to not offer a return option to any customer. This includes our right to not accept any return when we have determined that there appears to be intent to do harm to NonprofitComputers, the return appears to have abnormal circumstances, the customer has already returned a computer and wants to return another computer at a later date, or the return appears to be an abuse of our policies.

Computer software is not refundable once an order has been placed. Since most software licensing is now delivered online and the license may have been issued prior to the purchaser receiving it, once a software order is placed, it is not refundable at any time and for any reason. NonprofitComputers is not responsible for system/software incompatibility, and incompatibility issues do not qualify for returns. Customers are encouraged to contact the respective software publisher for answers to technical questions, such as versions and minimum system requirements prior to purchase.

Product Return Procedure for Refund:

• Customer wishing to return a hardware product must apply for a return merchandise authorization number (RMA) within 30 calendar days of receipt of the product by contacting NonprofitComputers.
• To receive your RMA contact us and describe in detail the reason for your return. Please be specific. One of our agents will contact you with your RMA number.

Physical Damage Policy

Physical damage to any product purchased at NonprofitComputers will effectively void warranty coverage as well as any return/refund/money back guarantee policies. Physical damage includes but is not limited to improper handling and/or any other type of damage sustained by irregular usage.

Recovery Media

Most computer systems no longer include and/or are not shipped to Customer with “Recovery Media”, for example, Disks or CDs used to restore your computer system to it’s factory state. Most do not include Operating System disks, for example MS Windows. This is not specific to systems purchased from any one company, but now standard practice throughout the entire industry.

However, some manufacturers include software on the hard drive that creates recovery media for you. This allows burning your own set of recovery CDs or DVDs – all you need is the blank media. Inclusion of such a recovery utility varies by manufacturer and model; not all manufactures and models include such a utility and NonprofitComputers does not disclose which systems may have that recovery media. For those that include such a utility we recommend you create your own set of recovery media. However NonprofitComputers is not responsible for recovery media in any form and customer should assume that it is not available for any computer purchased from NonprofitComputers.

Definition of “Recertified” and “Refurbished”

The terms refurbished and recertified are used interchangeable in the industry to describe products that were once in use and then returned their manufacturer, financial company, leasing company, or other asset management provider. These products are inspected, brought back to original manufacturer’s specification then tested and repackaged for sale. Some products are refurbished/recertified by manufacturers and others are refurbished/recertified by qualified third party partners. Refurbished/recertified products represent a great value and we offer them with confidence knowing that every product has been thoroughly tested and examined.

Processing Time

Most orders are processed within approximately 3-5 business days, provided the items are in stock and there are no problems with payment verification. Orders are not processed on weekends and holidays. We do not guarantee processing time. If we provide an approximate or estimated processing time, it is for your information only and may not be accurate or may change.

Backorders

NonprofitComputers may find that it does not have your ordered computer in stock. We will never purposely charge a customer for an item that we do not physically have in stock at the time of purchase or where we have been notified by a distributor, vendor or affiliate that the item is “Out of Stock”.

Occasional inventory discrepancies may occur. In that instance, we can refund your credit/debit card for the item, along with any applicable tax fees and shipping charges. An email will also be sent to alert you of the situation.

Order status

NonprofitComputers will keep you informed of your order status via e-mail. All tracking information will be emailed after your order has been shipped. You may also acquire your order status and other updates by contacting us. We do not guarantee the status of an order or of delivery tracking. If we provide this data, it is for your information only and may not be accurate or may change.

Security

Security is our number one priority. All online transactions are sent through our secure server and encrypted. If you order over the telephone, only trusted, authorized employees will process the payment to make sure your information is handled with the utmost level of security.

Privacy

NonprofitComputers respects your privacy. We will not sell or release your information to anyone except as outlined in our privacy policy found on our website.

Change Orders

You may request a change to your order provided that the order has not already been processed and shipped. Please contact us during our hours of operation to request a change to your order. We strongly discourage sending change order requests via email because it is unlikely we will receive the message in time to make an adjustment due to the sheer volume of emails we receive each day.

Cancelled Orders

You may request that an order be cancelled provided that the order has not already been processed and shipped. Please contact us during our hours of operation to request an order cancellation. You will receive a credit for the full amount to your credit/debit card in approximately 1-2 business days. We strongly discourage sending order cancellation requests via email because it is unlikely we will receive the message in time to void the order due to the sheer volume of emails we receive each day. Once an order has been shipped, it can not be cancelled.

Resellers

We do not currently have a reseller program. NonprofitComputers offers our lowest possible price, and offers these discounts to all of our customers through our website. NonprofitComputers is a reseller to end user customers and does not accept orders from computer dealers, exporters, wholesalers, or other customers who intend to resell the products offered by NonprofitComputers.

If you are a California nonprofit and are tax-exempt (from paying sales tax), please contact us and we will provide a Sales Tax Exemption form that you can complete and return with the appropriate documentation.

Product Listings

NonprofitComputers strives for accuracy in all item descriptions, photographs, compatibility references, detailed specifications, pricing, links and any other product-related information contained herein or referenced on our website. Due to human error and other determinates we cannot guarantee that all item descriptions, photographs, compatibility references, detailed specifications, pricing, links and any other product-related information listed is entirely accurate, complete or current, nor can we assume responsibility for these errors.

NonprofitComputers does not guarantee color deviations, the size and configuration of computers (tower, mini-tower, desktop, ultra small form factor, etc.), and other variations. We recommend that you do not use our product listings as a determination of such colors, sizes, and configurations. If you would like a specific size computer (tower, mini-tower, desktop, small form factor, ultra small form factor, etc.), you can place your order over the phone and make your request. Requests are informational only and we do our best to meet a request. However, even with a request, NonprofitComputers does not guarantee color deviations, the size and configuration of computers (tower, mini-tower, desktop, ultra small form factor, etc.), and other variations. NonprofitComputers does not accept returns on any order with more than two computers. The size and configuration of computers delivered does not change our return policy.

In the event a product listed on our website is labeled with an incorrect price due to some typographical, informational, technical or other error, NonprofitComputers shall at its sole discretion have the right to refuse and/or cancel any order for said product and amend, correct and/or remove the inaccurate information.

Additionally, all product information and/or specifications at NonprofitComputers are provided as resources to customers looking for additional information and/or professional opinion. The information may also be available at the website of the manufacturer as well as countless other online websites. NonprofitComputers does not assume responsibility for the information and/or representations included in the information on our website.

NonprofitComputers makes reasonable efforts to maintain the accuracy of competitor product and pricing information displayed on our website. Manufacturers and retailers can change their prices at any time and offer specials and discounts that were not available at the time we gathered our information. Therefore, we do not guarantee that any competitor pricing and/or product information is correct. We encourage users to conduct their own research prior to purchasing. NonprofitComputers cannot be held liable for any actions taken based on the competitive product and/or pricing information provided on our website.

NonprofitComputers shall not be held responsible for any loss or damage, or other liability resulting from such information. To report a pricing error, please contact us.

Product Revisions

NonprofitComputers is not responsible for changes or variations in product specifications and/or physical appearance. This may include changes between the order that you placed and the product that is delivered. Prices and specifications are subject to change without notice. In the interest of our customers, NonprofitComputers puts forth its best efforts to ensure that all product information is up-to-date and factual. Unfortunately there are varying determinates which, although infrequent, could cause the information on our website to become outdated or incorrect without our immediate knowledge. This includes but is not limited to new versions or revisions, color deviations, size and configuration of computers (tower, mini-tower, desktop, small form factor, ultra small form factor, etc.), retail package alterations and other variations that may be considered inconsequential by the manufacturer. 

NonprofitComputers relies on the manufacturers, distributors, and/or other vendors to communicate these differences. Presently we have no way of alerting customers prior to purchase in the event the manufacturer, distributor, and/or vendor fails to do so. Consequently, NonprofitComputers will not be held responsible for product revision changes.
