The NES Classic Edition, Nintendo’s tiny retro console remake that’s next to impossible to find in stores, is fetching more on eBay than modern-day systems from Microsoft and Sony. In terms of sheer volume, however, the PlayStation 4 and Xbox One continue to lead the pack by a wide margin.

According to statistics provided to Polygon by eBay, a PlayStation 4 was sold every 20 seconds during Black Friday in the US. In comparison, an Xbox One was sold every minute during the same period while the NES Classic Edition sold at a rate of one every two minutes.

On Cyber Monday, however, the tables were turned in favor of Microsoft.

eBay says Xbox One sales quadrupled in speed with a console being scooped up every 15 seconds. Sony had a solid showing as well with a PlayStation 4 being spoken for every 30 seconds. Sales of Nintendo’s retro machine remained flat with a sale tallied every two minutes.

It’s worth reiterating that inventory of Nintendo’s system is virtually non-existent while supplies of the other two consoles are readily available.

Jesse Kiefer, eBay’s General Manager of Deals, told Polygon that in addition to the aforementioned consoles, the site sold a 12-month Xbox Live Gold membership every six seconds. Kiefer added that Sony’s Dual Shock 4 wireless controller was among their top five selling electronics on Black Friday.

In reaching out to Nintendo for comment, the company acknowledged to the publication that its NES Classic Edition is a hot item and that they’re working hard to keep up with consumer demand. There will be a steady flow of additional systems through the holiday shopping season and into the New Year, the company said.

Nintendo encouraged shoppers to check with their local retailers regarding availability.
