The advice is just to do this, just like you are really dealing with selling your players, for example pretending that you want to sell him a rare/unique item. Just tell him and ask if he still wants POE Items , no one will doubt you.
If you buy from a big store, but the risk increases, you may find yourself on the GGG radar. I prefer to use mmoah.com, which is a player-to-player market where you can choose which trading objects to trade. I also like the layout of this website - I feel very comfortable buying there.
