I've known a few people who printed coupons that turned out to be unacceptable. I don't know which site it was, though.
You might want to consider just getting the Sunday paper. That's where our coupons are, and I find that I can save a pretty good amount. Our local store just started giving triple on coupons under a dollar, so that works well.
