Okay I was about to vendor some trash when I came across this item!
Thick Hide Pack - Item - World of Warcraft
Now alot of lowbies won't know where this item comes from, they'll see a cheap 14 slot bag on the AH and nab it
As you can see on WoWhead this item sells in AH for 22g while only costing 12g on on mine it sells for 35 for some reason almost tripling what I started with
