Happened to me once as I stumbled a good deal on fb, looks legit with "good review" and has a physical store and picture on google maps.. We thought they would never scam whilst sponsoring some of the biggest esports talent in the scene: n0thing, LS, Thorin, Monte, etc.. I just finished the first 2-3 hours of the game and it is getting more and more addicting the more I discover and learn.. It isn't a scam if you give them your money and they do exactly what they said they'd do.

Just stick with reputable companies and you'll be fine .... I've used that site a fair amount for buying physical switch games and always found them reliable with competitive pricing..
