This patch will enable Broker_GarbageFu to get item value from WoW itself rather than relying on external addons like Auctioneer and GarbageFu_Prices.
Only tested against Broker_GarbageFu v3.0.23-beta which you can find here.
Installation: Just unzip this into your Interface\AddOns folder and let it overwrite the old Vendor.lua (make a backup first if you want.)
FAQ:
Q: Does this patch disable external addon support?
A: No, GarbageFu will only use this patch if it can't get the item value elsewhere.
