I stopped by WalMart on my way home from work to get some groceries and decided to stop by the ammo counter. The ones I noticed: 22LR 550 pack (Fed and RemGB) went from $19 to $20. Fed Champion .40 100 pack went from $27 to $28. Not a huge increase, but it seems like they just raised prices 6 months ago. The Fed Champion 9mm 100 pack is unchanged at $20. I suppose one of these days I'll have to suck it up and make a huge bulk ammo purchase online.
