Both the gray and red-blue versions will be available -- while supplies last, of course. Obviously they won't last long at this price (we're talking minutes, not hours), but if you get there right when the sale starts, you should have a shot at it. As you might expect, it's one console per customer.

Let me be clear: This will briefly melt the internet. This is by far the lowest price ever for the Switch, and I have no idea whether Facebook Marketplace will be able to handle the load. Fingers crossed -- but be prepared for glitches. (And don't shoot the messenger. ?)
