There is a packaged goods premium on stacked stuff on the auction house? Now that's interesting. Makes sense on leveling goods I suppose, though. You don't want stacks of 3 or 6 or whatever, you want nice, easy stacks of 20. How well does this transfer to other items? I recall end-game enchant stuff selling for more indivividualy due to not wanting to store the stuff or resell the leftover mats back on the AH. Still, its about a 42.5% profit if you buy and resell at a 50% markup due to the AH taking their cut.

Its your time though.
