You can make edits to your prize information in the prize closet

In vPromotions, you can edit your prize information. You maybe not be able to edit all information if that prize has already been assigned to a winner, but most of the information can be edited. So if that client comes back to you with another 5 pairs of tickets you can give away to that big show, don't create a new prize, just edit the quantity of the one you have!
