We shop at any of the chain grocery stores, the bread outlet, Costco (a lot there), Sav-A-Lot, and the farmer's market in season. I shop the sales at the grocery stores, and try to combine with coupons. I am pretty vigilant about comparing unit costs on generics versus brand with coupon and/or on sale.
We are probably at the store 1-3 times a week.
I would guess we spend about $75 / month on groceries for a family of 3, me, DH and 4 yo DD.
Other things we do include...
