Guys. forget all the disability aspect of this thread and focus on this:

Does the game need a buyback feature? Cuz it sounds like if the game had one, threads similar to this (as in "I bought this by mistake" and not "this is unfriendly to "insert disability here) would not show up often.

I know I'd welcome it. I play SWTOR and I can say having nearly 2 days to get a refund from a vendor for almost all different currencies used to buy an item is a godsend.
