I’m slowly building up some stock on classic to sell. I keep 10 gold on my AH character and everything else I’ve been shifting off to a banker alt. I spend the 10g, replenish the supply (and keep 10g I’ve earned back, on me) and it seems to be working out quite well so far. I’m also still doing some snipes on the auction house and getting things for below vendor cost, so it fills in some gaps.
