The NES Classic Edition mini-console is going on sale today, November 11 across the country. It should be in major retailers like Target, Walmart, GameStop, and Best Buy. We already know that it will go up for sale on Amazon at 2 pm PT / 4 pm CT / 5 pm ET and we also anticipate it selling out in a matter of minutes.
You can attempt to secure one right now at GameStop.com as they have put some up on the site. There are various bundles, but as of this writing there were still some regular ones at $59.99 listed as available. Good luck!
