I have more than one friend who works at Wally World.
A couple who are not on the floor stocking shelves, in fact.
"We will not be ordering more..." with regards to ammo most likely means they've stabbed the "we're out" button on the ordering system and that closes the gate on stabbing it again for more.
Otherwise the store could end up with so much of a particular kind of ammo they'd never get it all sold short of taking a loss on it.
Wal Mart doesn't sell at a loss. Ever.
