When you buy a club and sell it back you only get a portion back. To expect a full refund when you used the thing is rather ludicrous, don’t you think?
Like alosso said, per the T&Cs they owe us nothing. But they're bringing the Flash avatars (slowly) over, and giving those to us for free if we had them on Flash. So it would be nice if they did that for the stand bags also.
