The other day I picked up the Gotham City Starter Pack for my Batman-styled hero. One I had not yet created I bought it while running my Superman based character. So now, I have that Batman styled character created now, and I tried giving him the Pack via the mail system, when running the Superman-based character. But it didn't take. Just got error messages. Do you trade/gift between characters on the same account via a method other than the mail system?
