9 out of 10 times that I find good coupons for stuff I need, I go to the store, purchase stuff I need, forget to present the coupon at checkout and then curse myself the whole way home for paying full price.

Today? Found $2 off coupon for hairdye. I need hairdye. I also needed ingredients to make pasta salad. Bought all of it. I am home now, coupon is still unused in my wallet. WHYYYY?
I saw this lady in the supermarket the other day that had a wallet full of coupons and used about 30 of them at the register. I was sooo impressed.

I do the same damn thing. GRRRH.
