Can I still return purchase to Fry's if the receipt is lost?
Without receipt, you will most probably get a store credit for the lowest price for which item was sold within the last 30 days (or 90 days). I only remembering returning one item to Frys without receipt and thats what they did but this was few years ago. Dont know if policy has changed recently.
As mentioned, if paid via CC, they should be able to look it up. Or if you bought the item using your phone number (frys uses phone numbers to look up customers), they can look it up that way also.
10 + 10 = 100
If you disagree with me or think that I made a typographical error, then you are not thinking right. Think Again.
