cannot purchase item

[LiniKoo]

when i try to purchase items from a store belonging to one of the players, i am sometimes unable to. sometimes it takes a couple of clicks before the item is purchased, but in some instances nothing happens. i would right click to purchase the item, like i always do when i purchase anything but nothing happens. this has happened to me more than once.

Not enough money?

My Guess is Store Lag, like when the gold-sellers cause lag in Guild / party / and whisper chat.
