Another super simple plugin. It will attempt to buy any item from the list that you set, every "Buy Interval" which you can set. Probably best to do this with wrotation, without setting a fightclass.
The idea behind it is to leave your char afk with the vendor frame open for a limited availability recipe you want and it will buy it as soon as it comes into stock.
Things I may add:
Only buy up to X amount of an item
Mail items in item list to X char then return to vendor
Move to a safe place until you want to recheck if limited supply item is available
DISCLAIMER: If you add in an item that is ALWAYS in stock it will buy 1 of it every buy interval meaning it will drain your gold until your inventory is full or you are out of gold. I am not responsible for what you add into the snipe list.
Again, this is a .cs file, edit what you want in your fav text editor.
Note: I created this because on vanilla i needed a limited supply recipe and it was extremely overpriced on the AH. Please don't overuse this and ruin it for everyone.
