Hot Coupon World?

I have to tell you that I was baffled by the system at HCW. I thought it would be an excellent way to trade coupons for things that I might use, but after trying to navigate the web site and determining that I'd have to trade on a large scale to make it worth it, I have decided to continue to order through The Coupon Clippers. I have given up all hope of decent coupons in the Times Free Press, and The Atlanta Journal no longer delivers to this area due to gasoline costs. The Coupon Clippers has been working well for me, and I definitely recoup my costs by using the coupons. The only issue I see recurring is that the expiration dates seem to be rolling around much more quickly. For instance, in this Sunday's paper (7/6), most of the coupons expire on 7/31. Perhaps they are trying to discourage swapping coupons or coupon services? What do you think?
