+1 this. my bag is full of collection items. with only 20 slots and collection items taking up as much as 6 slots each, there is far too little room in the backpack.

they indeed do not take up space btw ;)

They take up slots, it seems, but not weight.

I've 9 collection items, 5 voucher stacks and 1 quest stack, 2 stacks of essences needed to upgrade spells, 1 stack of sparks, 2 pots of paint ( proberbly useless after 1st bag ), 4 slots for potions, 1 for food, 4 for orbs ( though I've one lot of orbs in AH ), that leaves me 2 slots and if no one buys the AH orbs, only 1, if I get another collection item I'll be full when the potions in AH come out, how do I collect more collection items or bags if full?.
