How to get started with RMT?

Hi, I wanted to start doing RMT but Im not sure how to trade items safely now. Last time I ever bought or sold items was in 2020 when you could just list an item on flea and then they would trade you your goods but from what I remember BSG cracked down on that

Depends on items, if you want to sell money ask the customer to put scav junk box on flea or ledx/defibrilator, on most of the other items bsg increased selling tax by a lot and since they blocked selling most of the end-game gear on flea there`s nothing you can do but bring items in the raid and carry customer to the extract
