Up until recently, I had not noticed the 15% tax the trading post places upon successful sales of items, due to selling a bunch of stuff at once and never noticing the difference in actual money gained versus the price I had listed it at. When I finally started selling some things individually, I began to notice that money was being taken off of my trading post sales and vanishing into the aether. Thankfully, my friend who had gotten me into Guild Wars 2 mentioned that there’s a 15% sales tax on the marketplace. This was news to me, as nowhere in the trading post UI does it say that 15% of your sales price is being taken. I understand the reasoning behind having the tax, as otherwise the currency’s value would drop like a rock, but having the only hint of it be “Projected Profit” is extremely vague. I had thought for the longest time that that box referred to the sales price minus the listing fee, and showed you the profit you would actually make if including that. Nowhere in game, unless it’s somewhere extremely vague and obscure, is this sales tax mentioned. Changing it from “Projected Profit” to something like “Projected profit after 15% sales tax” or “Projected profit after <amount being removed from sales price> sales tax” would clear up a lot of confusion.
tl;dr: Change “Projected Profit” text to “Projected profit after 15% sales tax” or “Projected profit after <amount being removed from sales price> sales tax” to make sales tax more obvious.
