Hello, so i have a question i want to sell games on this site, but i dont know how much i need to deposit to your website to have access selling games, can you help me out with it? also if i buy access selling games do you take any fees from selling games?

To deposit and sell game gift you have to purchase a $50 premium, details at: https://dispenser.tf/view_contribution/

There is a 0.25-0.5% fee for selling items in market. But if you make a "traditional trade" (direct link trade), you pay no fees.
