Have you seen what newegg considers refurbished and their policys?
I couldn't find it but I swear that I have read on their site that refurbished can mean several things including items that have been returned (not sent to the factory for testing, just repackaged and resold as refurbished). I did find this. Among other things, only 7 days to return a cpu.
Refurbished Items
Newegg.com does not test any product, including Refurbish items. Refurbish components are therefore only tested by the original manufacturer. Due to the varying quality of manufacturer testing, YOU ARE TAKING A RISK BUYING REFURBISH PRODUCTS. Refurbish items are OPEN BOX products that contain components that have previously been owned by other clients and returned to Newegg.com. These products are sold considerably under cost.
Newegg.com guarantees all refurbish products for 15 days. CPUs, however, must be returned within 7 days for refund. All refurbish merchandise should be considered OEM "barebone" parts. Barebone means Newegg.com can only guarantee the item by itself, no other accessories. Despite what the product's description indicates, refurbish merchandise may not include all of the accessories mentioned on our website or the manufacturers. Newegg.com is therefore limited to the barebone part of the item itself. Please do not be upset or surprised if a refurbish product does not contain any cables, manual, software, drivers, fan, et al. Newegg.com will not send you any missing accessories, even if it is an essential part.
Newegg.com certainly does not like to discourage sales, but only experienced pc enthusiasts should consider refurbish items that know how to deal with possibly missing accessories. Please only purchase refurbish products if you are willing to resolve defects and/or know how to obtain missing accessories.
Refurbish items are not for dealers. We therefore reserve the right to cancel any applicable orders which may violate this warning. We are simply discouraging those who want to take advantage of this program as it is aimed towards the end user.
Refurbish products do have considerable higher return rate than brand new items. If you are just looking to get a good deal, please only buy new products.
YOU ARE TAKING A RISK BUYING REFURBISH PRODUCTS.
Sounds pretty risky!
