Coupons are totally worth it! My record for savings on one trip is $40. On average, I save about $10-$20 per week. That's like $780/year. I don't find that Costco and Sam's Club are really wort...

You gotta be careful with coupons, though. Sometimes the sales the store has beat out the coupon.

Then use the coupon in addition to the sale and save more!
