Speaking to a vendor brings up a vendor panel. Vendors will have some or all of the following tabs:
- Buy: Purchase items. Hover over items to see statistics. Stats listed in green are better than those for the currently-equipped equivalent item; red stats are worse.
- Sell: All vendors pay the same price for items. Items sold by vendors can be sold back for 1/8th of their original value.
- Buyback: Items sold to a vendor may be bought back from any vendor, provided you have not left the zone or logged off since you sold the items.
