With Dota 2 items, TF2 hats, CS:GO guns, and even sets of trading cards, there’s no doubt that Steam loads up your profile with tons of cosmetic goodies. Now they’re making an effort to make sharing those goodies with your friends more easy with trade offers.
Trade offers are proposals for item swaps that you can send to your friends, even if they’re offline. They then have two weeks to check out your trade and accept, decline, or send a counter-offer, removing the need for both parties of a trade to be online at the same time. Now you can fuel your Steam Badge addiction without the messy business of talking to another human being!
