If only Alterac Valley was possible.
By now absolutely everyone playing Free to Play should know this, but in case they don't, here's a tip I meant to post LONG ago, but did not get around to. For every city faction you get revered with, you can buy a 16 Slot Satchel. There's a total of 6 bags that you can buy, enough to fill your bag slots and 2 in the bank as well. Alliance, however, can also get 2 more 16 slot bags, the Harpy Hide Quiver and Gnoll Skin Bandolier, from Gaelden Hammersmith, that sadly Horde cannot get.
Each city has their own version of the reputation satchel.
Ever find yourself stranded while farming, leveling professions? No durability? Forgot that damn Skinning Knife again? Well, there's no need to run back to org as of Cata, thanks to the Dungeon Finder system and Cata's overhaul of Deadmines! The Vend-O-Tron D-Luxe, added in Cataclysm to the entrance of Deadmines, is a godsend for those moments. Simply queue up for Deadmines, Enter, grab the stuff you need, repair, and leave right back where you were. No running back to the city.
The best thing to happen to Deadmines.
