I do have several things that are in stacks of 99, but I don't want to put them on the markets in case I need them in the future. Mayhaps those items will be worth a lot more in an upcoming patch.

Hehe.. I'm honestly not trying to find a way to get rid of this stuff, rather, trying to find more places to store it.

As it seems now the only solution would be to level up 6 alts until they can have retainers (I already have one alt with 2 retainers) and then transfer items around. Mon Dieu.. It's going to take a lot of time to transfer things between alts since I can't transfer them directly.

Thanks for all the replies!
