An Amish store opened up close by that sells "seconds", like dented cans, etc. for a lot less than regular store prices. They also are the only place I can buy #50 bags of organic corn and hard winter wheat for long-term storage.
Backwoods is correct regarding the drug stores like Walgreens. Milk and other food stuffs are often found there at much lower prices than the supermarket.
(Backwoods... about where in VA are you located? I'm close to Lynchburg)
