Guild Wars 2

If you post an item for sale at 1 gold, the listing fee is calculated at 5% or 5s.

When you actually sell the item, you receive 90s, not 95s as you would expect

It seems the listing fee is being charged twice, or its possible this is intended and your communication on what the fees involved will be is unclear.

This became apparent when I sold something for 7g and made significantly less than I thought I would when picking up. -.-

There’s a 10% tax on the completion of a sale. If you’re selling an item, make sure to add in 15% to cover the fees.
