Wal-Mart has kept their prices the same since last December instead of raising them to reflect the prices every other ammunition seller in the country was charging. They could have greatly increased their profit margin by increasing prices for the product they sold during the time of massive shortages in this country, but they did not.
Now you begrudge them for what seems to be a totally reasonable price increase inline with standard business practices. They have been more than fair. If you don't like their business practices, shop elsewhere.
Funny, over the last 4 months, price's at my local wallychina have gone up quite a bit on ammo.
