More than 3 ?

Can you have more than three retainers? It will not let me purchase a 4th one

You pay for each retainer after the first two.
But at least it's account wide.

the third one is paid for but will not let me get any more...the two I think you get free and the third I am paying for.

I figured it out, I just could not do it in game.. .geesh..
