Coupons

I ALWAYS jump on the bandwagon late. This was true for capris, those large pearl necklaces with a satin lace tie in the back, pilates, blogging, and a whole host of other things. It's advantageous because things are cheaper then, but it means I'm constantly behind-the-times. I'm ok with that, though. (Side note: ironically, sometimes I jump on first and start the trend, but never get credit. I'm not bitter. But vinyl, for instance? I was in the first wave, promise. Due in part (or entirely) to a Christmas present from my BFF in Auburn. Oh, and the random coloring-strands-of-your-hair-with-highlighters back in the seventh grade? All me.)
But back to the topic at hand.
Everyone's blogging about couponing these days. I tried SEVERAL times a few years ago, and it never seemed to work. I kid you not. They'd forget to scan the coupons or some other bizarre occurrence, and I was left to either be That Customer, or say no prob and try another day. I figured 3 times meant it wasn't for me. But now I've decided to try again. I've had luck with coupons for baby formula and the target coupons, so maybe the stars have aligned better for me now.
So, the point. I know there are TONS of sites where you can go print coupons, and I'm wondering what your favorites are? I want to have that feeling of success of spending only $70 for $200 worth of groceries. And so I'm jumping on the bandwagon. Late. Again.
