Yeah but so what? They can also go as low as $15 so it'll just depend on the package size. I mean frankly, they are the ones who need it most and OP is clearly in a position where they are able to take some kind of L trying to sell it.
May as well be a good guy and pay it forward. Few around the states would be likely to buy it when the availability from official sources are just simpler and safer.
Besides, I bought a guitar from eBay from AUS. If they can charge me only $217 after shipping and the guitar itself, then a Steam Deck can get a nice price too ;)
