Surely it depends on how far one must travel to the stores and how much the savings are. I have two supermarkets no further than three blocks away, and about a half dozen small markets, bakeries, butchers within 8 blocks, so it is no trouble to go where the deals and/or the desired quality is.
I try to walk frequently (so as not to have much to carry) to the two closest stores. There is no gasoline involved, and I get a bit of healthy exercise. I have a short list for today and will visit both stores. I heard recently that urban dwellers get more walking exercise than suburbanites. Living close to things we also can save on gasoline and car usage.
