Economic Stimulus Checks (again!)

I wrote a while back about Kroger and Sears offering an extra 10% if you bring in your check and convert it into a gift card. I recently found out that Albertson's is also offering this deal and that at least for Kroger and Albertson's that you don't actually have to bring in your check. You just have to buy a gift card in $300 increments. I'm considering doing it at Kroger since we do a fair amount of our shopping there anyway but I'd only buy $300 worth. We are expecting $2100 and I sure didn't want to commit that much to Kroger!
