I use coupons and my reusable bags. We are down to 3 of us here and it's hard to buy in minimal amounts.
Went to Sam's Club last week- haven't been there in ages. It felt good to say we don't need to buy in bulk anymore. At one time I shopped there almost weekly. With a large family of 9 I knew who had the sales, etc. I went to 2 to 3 stores a week and got my shopping done for $100 a week after coupons. Now- $100 a week for 3 of us, after coupons too.
