Keep in mind that with digital comics you generally don't 'own' them. You've licensed them and you view them as much as you like so long as they don't cancel your account or shut down their authentication servers, etc. IIRC, you won't be able to loan them to a friend either.
Think of it more like buying something from an MMO at the cash stop instead of buying a real, physical comic. If you're ok with that, you should be good.
