There are TWO forums that I frequent to get the best deals! The first one is AFC (A full Cup). There are forums for each store, and areas to find coupons, trade coupons, etc. You can meet lots of other couponers and share tips + deals. Best of all, its FREE. No credit card required, no payments ever! Here is the link to A Full Cup, head over and sign up or check it out and then sign up so you can begin chatting, commenting and my favorite- TRADING COUPONS! :
The Second Forum I frequent (and spend WAAAAY too much time in!) is HCW (Hot Coupon World). It has the same things that AFC does, but seems to be a lot bigger. (so, Its a little more overwhelming in my opinion). HERE is the link for HCW if you want to check it out. There is also a banner in my right side bar for Hot Coupon World.
