Newegg is an excellent retailer.
Here's an quote from their website;
"Money Back Guarantee- Refund period
All merchandise unless otherwise indicated may be returned within 30 days from the original invoice date for a refund. CPUs must be returned within 7 days from the invoice date for a refund. A return authorization number is required for all returns. A 15% restocking fee may apply. Additional deductions may be made for CPUs returns to reflect the current market value. These terms apply to all refunds. All new products offer at least a one year warranty except for OEM CPUs which have a 30 day warranty. Customers must inform Newegg.com of any order discrepancy within 7 days from the invoice date so that we may investigate and resolve the situation accordingly.
1. NewEgg.com SATISFACTION GUARANTEE - NewEgg.com offers our customers a 30-day satisfaction replacement or refund guarantee on all purchases, except:
7-day replacement or refund guarantee on all CPUs, including refurbished processors. All other refurbished merchandise has a 15 day warranty period.
Note: For CPU, base cost will reflect current market price, and 15% restocking fee will apply after this adjustment. Therefore, total refund is subtracting. "
Newegg policy
If your cpu arrives DOA, send it back within 7 days for a replacement it not looking for a refund. I believe that the 15% restocking fee only applys to refunds.
