I read a blog today that makes me want to rethink my earlier thoughts. Okay, it still does not answer the time question, but it does show this is can be accomplished with most every shopping trip if some planning is done beforehand. It would seem that Toni-Lynn at the Grocery Price Blog is proof of this. In her post The Coupon Cupboard Virtual Food Drive and Mom It Forward she not only shows a recent receipt where she paid $3 for over $500 worth of groceries, she states she saves up to 98% on her trips every time.
