I want to introduce you a trading platform for games like Rocket League (RL) and Path of Exile (PoE, Exalted Orbs). But we still focus on the Rocket League because it is definitely more popular game. In the Rocket League you can buy items for money, earn items and crates, buy RL Keys - all you can trade with the Odealo trading platform https://odealo.com/games/rocket-league
