I agree. I do that all the time. Think about how much money credit card companies charge on their fees and interest, you will not feel bad of taking some advantage from them. Last time I bought my 770 from buy.com, I got $30 online credit and another $30 on my credit card statement. So $60 total discount, made my 770 price down to $92, not bad. My credit history is 100% clean, and never pay interest to them. All my credit cards have some sort of rebate and no annual fees.
