When the NES mini was released last year, they barely spent any time on store shelves before they were all whisked away by eager gamers and scalpers. Since the retro consoles were notoriously difficult to find in stores, some fans demanded that Nintendo implement a pre-order system for the inevitable SNES mini. Well, Nintendo listened… and according to an article from The Independent, some customers are getting their pre-orders cancelled due to the incredibly high demand.

The SNES Classic Edition was announced a little more than a week ago, and the retro gaming revival has already proven to be so popular that when pre-orders became available in the UK, all the consoles were sold out in just a couple of hours. Even major online retailers like Amazon and GameStop aren’t sharing information on when–or if–their stock will be renewed.

In fact, demand is so high, that some people have reported getting their orders cancelled even after they’ve already paid for them. Due to the immense popularity of the item, Amazon has sent emails out to those who ordered informing them that customers will only be allowed to buy one console each, meaning that any orders for multiple SNES minis have now been reduced to one.

Nintendo predicts they will sell more SNES minis than the NES from last year, although that may have something to do with the fact that they’ve produced twice as many of this year’s retro console. Nintendo has also stated that the SNES Classic will only be available this year and did not confirm whether or not more would be made in 2018.

For those who are lucky enough to pre-order SNES Classic Edition, the console will start shipping September 29th, 2017.
