Also, the biggest one may be -- if your prescriptions are currently somewhere else, and you transfer them to CVS, you'll get a GC for $25. This requires a coupon, though, and they come out intermittently. So keep an eye out for them. I had a coupon around here somewhere that I won't be using... if I can find it, I'd be happy to send it your way. (It does exclude certain states, though.)
It does take some time to figure out the ECB deals, and there's a bit of a learning curve, but it doesn't take too long to catch on. I'm one who has more time than I have $$, so I don't mind (I do my CVSing, and now couponing at the grocery, as one bunch of "time," and it's amazing how much you can save.)
Oh, and watch out. It's addicting. I didn't believe it when I first read the threads, but really... it is. Here's the link to next week's thread:

Good luck!
