I've started couponing very regularly now since everything is creeping up in price. We're trying VERY hard not to have to increase the food budget, and couponing helps tremendously. I cannot fathom how the "extreme couponers" get $1000 for $ 6.00, but I think part of it is what everyone else said....they're ONLY buying in bulk what they have coupons for. All of the rest of us are also buying meat, fruit, vegetables, etc. And if your DH happens along, well you're buying stuff that wasn't even on your list !
But I will say this, I've learned how to shop CVS with coupon matchups and getting the extra care bucks. We've got a great stock of shampoo, conditioner, mouthwash, toothpaste, floss, deoderant....all for pennies. So I'm VERY happy about that because those expenses add up.
I'll never be the "$ 1000 shopping trip for $6.00 person" because we won't buy things we won't use. And I'm not going to buy 50 boxes of corn flakes when we eat Special K. So, what I take from the shows is the "how to do it" and how to match coupons with sales. And I've learned a tremendous amount.
The other thing, if you haven't seen this, on The Krazy Coupon Lady's website, she has instructions for sending your out of date coupons for the military. Apparently the military bases will accept coupons up to 6 months out of date.

If anyone's interested , here is the link.

I've got my coupons, that I never used, and packed them up and they're all ready to send out....
