Nintendo Switch Lan Adapter $13

Found this adapter in the electronics clearance section marked for $21. Scanned it with the Walmart app and it showed $15. Went to the register and it rang up $13! Get one now before Super Smash Bros Ultimate comes out to get the lowest latency connection for online play. The last Nintendo Direct Video https://www.youtube.com/watch?v=fccgHnBQ0YM even recommended that you use one to get the best connection.
