FreeRefills 

FreeRefills is for automatic stocking of any items you want in your bags. When ever you visit a merchant, it will check to see if that merchant sells an item on your shopping list, and will pick up however many you need. Also your list will automatically be saved per charecter, per realm. You won't have to worry about your baby mage winding up with 3200 bullets.

Commands:
"/freerefills" or "/fr"

-- add [item link] # -- This will add the linked item to your shopping list, # is how many of said item you want to keep in your bags.
-- addstack [item link] # -- Does the same thing as "add", except it takes number of stacks, instead of individual items.
-- del [item link] -- Removes the linked item from your shopping list.
-- clear -- Clears your shopping list.
-- list -- Print your current shopping list in the chat frame.
-- overstock -- Toggle Overstocking. If an item is sold in stacks and cannot meet your exact requested amount, you can opt to buy slightly more (Overstock).

Known Bugs:
When looting items from the bank, partial stacks will be dropped into the first bag with an open slot. It won't always combine your partial stacks.
