Tag Match

Most NPC vendors buy items back at 80% of the item "value". A few select vendors will pay a full 100% of the item value. Portalarium calls this a "tag match". Any particular NPC may offer a tag match price for more than one item category.

To identify such vendors, simply see what a vendor will pay you for a given item, then see what a completely unrelated vendor will pay. It will help to have a single un-stacked item in your inventory, or you can control-drag a single item to the exchange pane. Items with a value of less than 5g will always pay full value due to rounding.

Note that what any NPC will pay for an item with a durability stat is affected by the durability. This is mostly important for weapons and armor. A weapon at less than 100% of brand new durability will sell for a lower price, but is still subject to a tag match mark-up.
