Three stores in particular. For food/groceries, I go to Food 4 Less/Kroger's. The food, especially the fruit are very cheap and they last pretty long. :D For clothing, it's a tie between Walmart, Burlington Coat Factory, and Old Navy. For anything else, it's either Walmart, Best Buy, or Staples. :P
I never go to walmart for groceries. I got sick from buying their meat one time. Never doing so again.
