You're going to have to learn how to trade I am afraid. I don't recommend just assuming you know what you're doing when you really don't, because then you'll just end up embarrassing yourself. You can only trade limiteds, and you also don't even have premium... So you can't trade either way. Look up YouTube videos to get started. But ensure you have premium, and ensure you buy at least 1 limited item before you even think about trying to trade.
I've seen my fair share of noobs asking one another if they want to trade, while they both don't have premium, and they both don't have limiteds.. It's rather cringe to watch them "try" to trade. Even though the trade hangout game specifies you can't trade without premium before you enter the game... which nobody clearly reads.
