I've found I agree with the DUmmies these days. Walmart sucks.
Not for the reasons they obsess about--I've just found in the last few years, the stores have really gone downhill; all the merchandise is always out of stock, and the associates are rude, lazy, and horrid in terms of helping you. I've found Target to have about the same prices with a much cleaner store, full shelves, and helpful associates.
