Only offered gold sub on one account?

So I've been watching the wow token prices for a couple of days and decided to pounce when they got to the "low" end (36k seems overpriced, but whatever). The first account I logged in and paid, but when I logged into my other four accounts (including my two rich ones) I wasn't given the token popup.

I don't think I activated them all at once with gold last time, is there a delay after you buy one token on a bnet?

I sincerely doubt I was mysteriously hacked and my gold wiped from 4 of 5 accounts.

I'm an impatient child, the others seem to be working 1 by 1 as the price goes up <.<.

Is it BtA like battle pets? You may not be able to with more than one account logged on at once.
