Guild Wars 2

Simple question so I expect a simple answer.

Can anyone tell me why pp doesn’t match selling price minus fee? It’s systematically lower at trading posts.

Thx.

You have a 5% listing fee (money you have to pay for listing the item). When you actually sell the item you have to pay 10% tax. The projected profit only reflects the selling price-10% tax. The 5% listing fee is paid by you and not by the buyer, so not seen in the projected profit.
