is TP collecting listing fees twice?
All i know is, when u sell an item on the TP for a certain value, that 5% of that value is taken as listing fee from your inventory money as soon as u place the item, and when the item sells 10% of that value is taken as sell tax. The money amount shown as Projected Profit is the value minus the 10% tax.
The 5% listing fee has nothing to do with what u get from selling the item becos it was taken from u seperately.
