Well I read about this a while ago on the central and over at Valerian's place, but I figured I better let you all know that you should put these codes into the Wizard101 site. What you do is log in and click on the redeem card or code button. Then type the following code words in:
Frog = 500 gold
Castle = free stained book table (for your house)
Summer Dragon = that dragon that everyone has
Magic = an amulet
Thanks to those who did the legwork on all those codes!
