My Wal-Mart is still ten bucks. I'm guessing someone got the shelves stocked wrong at your store.The price on the 9mm Federal aluminum was $15 a box tonight at Wally World, up from $10 a box just 2 weeks ago. Now I'm kicking myself for only buying 10 boxes back then when they had about 30 in the case.
