Sony revealed it’s eliminating one of the only ways for gamers to buy games for list price without having to hand over their credit card details — namely, in-store digital codes. So if you wanted to buy a game from an actual retailer, your only options now are physical discs or PlayStation cash cards.

Twitter user Wario64 revealed an internal GameStop memo that presages Sony‘s move, saying that the cut-off point is the beginning of April. Sony confirmed the date to GI.biz, specifying that DLCs, season passes, and the like would still be sold via codes at retailers. Any codes already on the shelves — in the form of those nifty little scratch-off cards you might recognize — would be deactivated at the same time.
