I decided to take the risk and buy the OP's steam random keys directly from this shoppy link: https://shoppy.gg/product/HBrL7fA .I used ethereum as the payment method and everything from my side went well beside nothing was changed on shoppy (they showed the payment is in pending). I contacted the seller on his discord channel for his help and was kindly enough to manually process the order (+ I got a bonus of 13 random keys for the vouch are you reading right now). The keys are indeed, random. A bunch of games that you'll probably keep in your library just for the collection (or maybe I was not lucky enough).
