Here we trade a lot to get more of the coupons we want... For example my dog will only eat Kibbles and bits dog food (ya she is a bit picky)... so when I know that coupon will be in the paper.. I will post I will trade for that coupon. I usually get a couple responses, thus getting a couple more coupons.

I also get two papers per week.. so that helps. I have two different ones in my area. So I get them both.

Also building a stockpile wont happen in just one trip. It will take some time.

Store brands sometimes wont have coupons. So if that is the majority of your sale ad. It may be hard to get a coupon for it.

Also the item doesnt have to be on sale before coupon would be worthwhile. I have enough things that were bought when they were not on sale.. coupons though made them very affordable.
