In our home, instead of stocking tomato sauce and tomato soup in the pantry, we buy cases of tomato paste (the little cans). If I need some sauce, I open a can of paste, add a little water, and then start adding the herbs I want to season it with. If I want tomato soup, a couple of cans, and a little more water does it. Of course the paste is also integral to other recipes (my barbecue sauce, for example). Point is, I stock up on one thing, and pay less overall, as well as minimize the impact on my pantry space.
BTW, those Sams Club meats as often as not find themselves being diced up with some vegetables, boullion and some seasonings, and being made into soup. Vegetable beef, chicken noodle, bean and bacon, minestrone, cheddar potato; we haven't stocked condensed canned soups - with the sole exception of cream of mushroom and cream of chicken for sauce bases - in years. Better for ya, no preservatives, and still cheaper.
