Walmart has cancelled all pre-orders for the SNES Classic, meaning US buyers appear to be back to waiting until the September release.

The company had the console on sale for about 30 minutes last week which, in the age of social media, was long enough for word to spread. While some buyers had since received cancellation notices, others had heard nothing until today’s official statement reading:

Unfortunately, due to a technical glitch, the Super Nintendo Classic Edition was mistakenly made available last Friday evening ahead of the official release date. We, regrettably, will have to cancel this item on your order. We know that this is incredibly disappointing to you, and we’re truly sorry for this mistake.

Credit card buyers won’t be charged at all. Those who used PayPal or a gift card will get a refund. There’s no mention of any goodwill gestures such as a gift card, discount or priority when orders do go live.

For now there’s still no official pre-order in the US before the scheduled September 29 release. The SNES Classic was on pre-order in the UK and quickly sold out, leading to some questionable eBay listing promising release-date delivery at inflated prices.
