Trading community PSA: CHECK YOUR TRADES FOR GUEST PASSES

Make sure you're trading for a FULL copy of a game and not a guest pass.

I've had people offer guest passes of CS:S, & Killing Floor marketing them as full games. Only to realize while in trade they were trying to rip me off.

Even with my due diligence I was recently stuck with a CS:S Guest pass since I didn't take the time to hover over the game icon to be sure it was a full game!

The only difference you may see is this: http://imgur.com/7aJwM

Please be careful and happy trading!
