Greer is waaay far out from Anderson, but the Acme General store in Downtown Greer has Mountain House #10 cans, I believe.
If I might ask, what particularly are you looking for? Freeze-dried foods for easy preparation? Foods with particularly long shelf life? Meal variety?
If you can afford the time spent, you might want to consider dehydrating and canning your own foods that you and your family know how to cook and enjoy to eat. Going by the maxim of "store what you eat, and eat what you store," the Mountain House meals (and other freeze-dried measl-in-a-can) might not be palatable for you and your family, and could be quite expensive if you are regularly going through them. Plus, some brands do not have a great shelf-life once they have been opened; you'll be stuck eating beef stroganoff for a week in order to not waste any of it.
IMO, I would first try to have at least three weeks of foods you regularly eat stored up, then delve into longer lasting staple (beans, wheat, spices, etc.). Store up smaller portions as to not waste any of your money, or buy in bulk and then divy it up into air and water tight containers. My wife and I are working on a menu of meals that we like to eat, and we're using those ingredient lists as a guide to developing our pantry and garden.
At a prepper conference last year, I met a local representative for Shelf Reliance. Their products seem pretty stout!
