Earlier this week, retailer GameStop announced that it received a new shipment of Nintendo Switch systems and would make them available starting on Wednesday, March 22. It seems some stores have started to sell their stock early, as online reports claim the systems are being sold in-store right now.

People on NeoGAF are reporting that their local stores received 10 units, and they're being sold right now, including at least one store in Houston, Texas. As always, your market may vary, so it's a good idea to speak with your local GameStop about stock and availability.

If you're willing to part with your gaming hardware, you could get a Nintendo Switch for well below its $300 price point. GameStop is paying $150 in store credit for Wii U and 3DS systems, $175 for Xbox One, and $200 for PlayStation 4 when you apply that to the purchase of a new Nintendo Switch. This means you could get the hybrid console for $100-$150.

This special trade promotion is good until March 26.

"The customer enthusiasm and response we have seen so far [to Nintendo Switch] has been incredible as we continue to sell through our supply of systems," GameStop merchandising director Eric Bright said in a statement this week. "We strongly suggest any customer who is still looking to purchase a Nintendo Switch, visit one of our stores as soon as they can. This new allotment will go fast!"

According to GameStop, Nintendo Switch sales have been "phenomenal." In fact, sales are so strong that the new system could outpace the Wii in terms of sales at GameStop.

Demand for the Nintendo Switch has been high and Nintendo is reportedly doubling the amount of units produced to meet this.

Nintendo has not yet shared any specifics on sales, but it did say the console is the fastest-selling Nintendo system ever in the Americas, Europe, and Australia. A third-party report said 1.5 million Nintendo Switch units were sold in the device's first week on the market, which means it is close to meeting Nintendo's first-month expectations of 2 million sales already.
