Why can't we sale free stuff. Such as the Zynga shirts and the Pop Sneakers. Mine says Free gift. So I don't see why we can't sale them.
I seen the Zynga shirt on auction. Yet I can't auction mine off. Which say's free gift.

Any help me understanding this is much appreciated and thank you in advance

Hey LoLLy due to a hack players were using during Zynga's time with the free gifts, when BVG took over, they simply removed the ability to trade all Zynga items labelled as free gifts. Some items however escaped that labelling and so are tradable.

I have a ton of barrel costumes and Zynga shirts that I would love to sell too, but they sit in my inventory looking at me as I look at them
