I see most of the people are discussing the issue based on good faith of the rebate providers.
For big companies it is a win-win situatation
1- many of the people do not apply to get the rebate (specialy if ther are under $10.00)
2- They can use any minor error on the form to discard the form and do away by apying it to customer
3- Some of the handlers of rebate program make it worst by just dumping the froms (either encouraged by the merchant or internal process).
I do believe that companies like Best buy or others realy have good-faith in providing the rebate. 4 out of 6 of rebates have been lost in the process and they do not accept the copies. Just try to return an item that you have used a rebate or gift card – there is no way that you can get that part back.
