Currently in development stages.
This is a simple addon that scans the AH for every item that you currently have one or more of posted on the AH. It then determines what you were undercut on and cancels any of your auctions you were undercut on where you can re-post the auction and still be above a set % of Auctioneer's Market Value.
'/um' - prints out all the slash commands
'/um scan' - runs the scan (you will be prompted when Undercut Master is ready to start cancelling
'/um config' - opens a small options window
