We shop at one of those low cost, bag-it-yourself grocery stores. I spend about $160.00 (U.S.) per month on groceries for a family of four!
My advice is plan ahead on your meals. I do so a month at a time. Each night of the week, is given a specific meat day. For instance, Mondays: chicken, Tuesdays: ground beef, ect. Add rice, vegetables, pasta or potatoes for the side dishes. I know exactly what were having at any given time without much thought. When you break it down, we only have, say, chicken, four times a month so there is no boredom. This works great, and my family really looks forward to Fridays; fish night!
I also keep 2 or 3 laundry baskets in the back of my minivan, to carry items from car into the house; this eliminates the need to ever have to spend time "bagging". Just place the groceries in baskets and transport where needed. - Submitted by Anna
