NX card recalls?

In the past two weeks I've been to 5 different wal-marts in 2 different states, and they all seem to have recalled their NX cards. The week before this happened I got a $25 card, and the following week when I tried to buy one, the cashier said they couldn't process it, and took the rest of the cards off the rack. After that, every other wal-mart just didn't have any to sell. Is this going on with any other wal-marts, not only on the east coast?

Maybe it has to do with the fact that Wal-Mart, isn't, and never has been on this list.

I work at Walmart, they did have NX cards. All NX cards are 'deleted' inventory, which means they sent it back to the company (Nexon).

Last time they had them on the shelves was about 3 weeks ago at my Walmart. I still hate working here...!

PS: I recommend trying BlockBuster's. The one in my area has a crapload amount of them. No joke.
