Valve continue to refine its digital distribution platform, Steam, by introducing a new feature called Trade Offers. Trade Offers allows gamers to suggest trade deals for inventory items, which can be accepted, countered or completely declined.
Trade Offers can be done without both friends being online at the same time, and it's also accessible through web browsers, so you're not just limited to being on your PC and in Steam. Trade Offers can be used only between Steam friends, but it could reach further than that in the future. Users who set their inventories to "private" will not be eligible to receive trade offers.
