Just thought I'd pass this along in case anyone out there is as big a cheapskate as I am. (doubtful ;-) ) I just got my Chase Stockback card, and went to www.stockback.com to register, and I discovered that anyone can join the program: you don't need to have a Stockback card to do it. It's a good program, from what I see so far. You get up to 13% rebates at some merchants. Buy.com for example, already pretty cheap, gives you a 2.5% rebate when you go through the Stockback site. And of course, you also get any rewards associated with whatever card you use -- it doesn't have to be a Chase card. If I'd figured this out earlier, I'd have kept my i-Card and just joined, since the i-Card rewards program is practically identical to the Stockback one, AFAICT.
