Just a friendly reminder that 'A Mysterious Valentines Card' restocks in the Neopian Gift Shop in large quantities at random times. You can haggle it for a lower price.
Check the Shop Wizard and the Super Shop Wizard to find the best price before buying.
Sending 'A Mysterious Valentines Card' to anyone on Febuary 14th unlocks the site theme for you and the person you sent it to.
You can unlock the site theme on your side accounts since it awards nothing except the site theme.
