As far as eating cheaply . . . Meijer's is the best bet around here. Wal-Mart is just fucking evil and their prices aren't quite as good. You can get good-quality stuff in reasonable bulk (not those insane things like twelve-gallon jars of mayo, but still something where you know you've gotten a good deal and that will satisfy the packrat within), plus which they sell booze (by which I mean both beer/wine AND liquor), which is always a plus.
