I thought one work around would be for my alts to purchase some thing from my main on the broker. I tried selling a cheap item at higher prices to basically transfer money from alts to my main, but it doesn't appear to have worked. My alts were able to purchase the item and the sale went through the broker (the money was taken from alts), but the mail with the notification of sale and cash never arrived for my main. So it looks like the broker took my cash from the sale but it never came back to my main. It's difficult to find answers to this question, but was this method not allowed?
