Tech Depot is the "web store" for Office Depot. One thing to be aware of is that except in exceptional cases, for an occasional "house brand" item, neither Tech Depot nor CompUSA "offers a rebate." The rebate deal is with the manufacturer or distributer of the particular product you purchase.

I've found both CompUSA and Office Depot among the more helpful in making sure you get everything you need to request your rebate, but in all cases I've seen it's the manufacturer you are dealing with when you apply for the rebate. In the retail store in my area, CompUSA has their checkout registers rigged to automatically print you a "duplicate original" receipt for items that are bar-coded as having a rebate offer. At most other places you have to specifically ask for a duplicate receipt, and you sometimes get a bit of argument - usually because the "clerk" you're dealing with doesn't know how to do it. It's still up to you to follow the rebate instructions exactly and to send your request for rebate to the right address with exactly the specified documentation.
