seen someone selling them so i wanted to say; don't buy them. at least, not for more than 70 cents. the way toyhouse works, you can pay 5 dollars to get a premium account for a month, and during that month you'll get 8 invite codes (2 per week) so the people selling codes for like 5 bucks are turning a profit in a way the site makers probably wouldn't approve of.

also! if you need a place to put your characters and don't wanna buy an invite, i recommend refsheet.net, which is totally free and way more easy to use.
