AH Scanner: This add-on will let you easily gather the lowest minimum buyout costs on the Auction House, and show them in a table, accessible through the slash-command /dmt
If the item was not on the auction house the last time you scanned, it will be flagged. In the future I hope to be able to let the user choose what to do with such cards, but for now it will keep its old value (unless more people prefer it to be set to 0 instead and do the math themselves on what they value the card as)
Card Trader: With the "Trader" button that is drawn up with the same slash-command /dmt, you can now specify what cards you are trading or looking for, and also find out what other traders want, which is listed in a table.
NOTE: It can take some time for the "traders" button to become enabled if there are many people running the addon. Please be patient (as it notes!)
Card Tracker (by popular demand!): Using the "Scan Inv" button will scan every open bag for (current patch) darkmoon cards. Using "Inv Table" will then open up the table that displays which cards you have and how many of them. The scanner should also lump together the same card into one quantity even if they are split into different stacks.
