you can trade for free without paying anything. just go to website and trade. or do it ingame.
stash tab trading is optional.
it has got benefits, but frankly, skins on a char has benefits too. ppl look more at you and you look cooler. more stash tabs are better, everything you can buy is better to have than not to have.
that is the principle of goods. they have to be of advantage or else noone would buy it.
what i want to say is: this game is fcking cheap dont complain.
