Do you have to pay for Poptropica membership and how much?

Poptropica is free to use, but to have access to all of the costumes and effects, and Early Access to the islands, there is a paid monthly membership. The 6-month membership as of 2013 is $19.95 USD, which is about $3.33 a month, charged to a credit card or gift card.

(Some items will remain yours even if your membership ends.)
