Walmart never has stuff on sale, thus the generic is always cheaper than name brand is with a coupon. If we would go to the grocery store where stuff is on sale, the rest of the groceries would be $75 more for the week. To go to both the grocery store to get the sale/coupon stuff only and go to Walmart for everything else, it would be $30 extra in gas.
Besides, we can not find any coupons for anything but junk and cereal. With the cereal, it is cheaper to buy the large box at Walmart than it is to buy the itty bitty boxes that are on sale at the grocery store 4 for $10 and usually $1.00 off 2 or 3 boxes (double coupons up to $0.99, so that is how they get away with not doubling.) Why buy 4 boxes of 10 ounce cereal for $8 after sale and coupon when you can buy two 24 ounce boxes of the same cereal for $3.89 each?
