Merchant Archive

I am trying to blow out the items on my vendor however i do not want to individually mark down all 500 items as with server lag and the three to four clicks per item it would just take too long to do. I wish there was a way to mark down the entire vendor 15, 20, 30% or select 50 items and mark them down.

This would also allow people to have sales for a while ex. 1 week then easily mark them back up after the sale. Kinda like a store.
