Walmart allowed this to happen. They were like, "Hey, if we pretend like this isn't our fault, we can sell thousands of dollars in groceries!"
It was so blatantly obvious something was wrong, they should have acted.
Now they are going to try and pin the blame on the government, and the government tries to pin the blame on the card contractor, and the card contractor is tyring to pin the blame on etc. etc. etc.
Anyway, Walmart bases a huge portion of it's income on EBT cards. If they denied EBT transactions, they wouldn't make a profit.
