Gift Cards and ingame Items (TF2,D2,CS:GO)?

and your suggesting this to steamgifts lol.

Nope, because part of the thing about this site is the only profit the winner will get is from having a new game. Those other items would quickly be sold or traded away.

No thanks, I can already see the site being spammed by 'nice' people giving away 1240 trading cards they collected.
Or worse, giving away TF2 crates shivers

hell no

not here that's for sure, but maybe someone will make steamcardsitemsandstuff.com

SteamItems.com would be a good place to do that.

You could start a steam group and run it yourself that way.
