Offline Vouchers are usable items that allows you to leave a copy of your character on the map to either sell or buy items when you're away. The shop you created will remain even if you leave the map or disconnect. The only time your shop will be closed is if your items sold out, met your purchase limit, server went down or if the voucher has expired. Each account can only utilize one of each voucher at once, meaning one merchant and one shopper, although the voucher is sharable amongst characters in the same account, it will not be usable if another already exist.
Offline Vending will have a timer to denote how much time remains on the shop

If you somehow forgot where you positioned your offline vendor, you can use a Shopping Catalog to locate it. You just need to remember the map where you left your character and at least one of the items you are selling/buying. Your vendor will show up as a white marker on the mini-map if it shows up on the catalog and you click on the vend name.
