buying notum wars after trial period

i have just started a trial period, do i have the option to buy
notum wars after the trial ended ? or do i have to buy AO and
then buy notum wars aswell ?
or can i just delete my account w/o buying anything and then buy
notum wars and start a new one ?

hell, i just want to buy NW at the end of my trial ..
i dont want to buy AO, and then order NW, wait a week or two to
have it shipped here, pay 20€ + deranged shipping, and all that
just to play a game in my meantime..

HORRIBLE !

Notum Wars contains the full AO client and a month's worth of free play. The free month is of course only available to new subscribers. :)
