The retailer reportedly "oversold" orders. The Zelda -themed Switch 2 is out this week, and Walmart has reportedly cancelled some pre-orders at the last minute. As highlighted by Kotaku , some buyers have apparently received a message from Walmart notifying them that their pre-order has been cancelled as the item is now out of stock. They won't be charged, but this information was only shared a day before the expected arrival, so they're no longer getting a system.
