So I just bought 60,000 more crowns. I currently have 84,711 crowns, so I can buy every area that is in Wizard101 (I've already bought up to Zafaria) and once that is done, Wizard101 is free for me until new worlds come out.
I will get back to you once I buy all the areas.
Sometimes I do wish we could get member bonuses for investing so much money though.
