Where is it okay to trade items, gift cards, etc? I couldn't find it under the forum tab. Or is it even allowed on the site? I have a few xbox 360 1 month gold membership to trade. let me know.

the official trading thread (and the rules) is here: Official Trading Thread - You MUST Read the 1st Page Before Trading *Rules Update 12/18/2009, see #15* (http://slickdeals.net/forums/showthread.php?t=879633)

however, in your case, you might want to go into an item specific thread for a better chance at trading Free 1-Month Xbox Live Gold Subscription Code *DEAD* (http://slickdeals.net/forums/showthread.php?sduid=17819&t=1911756)

we do ask that you review the trading rules first.

hope this helps.
