i have 6, but i'm not after them the same way i am avies.

to get the valentine's day sidebar, you have to either send or receive a mysterious valentines card on february 14th. the person who receives the card doesn't know who sent it, hence the mystery. once it's sent, it disappears and cannot be reused.

this is from grundomoody's petpage, which is an excellent sidebar theme resource.

You can restock the card at the Igloo for 53nps year round in batches of a dozen. You can restock the card at the Gift Shop for 250nps for the entire week preceding Valentines Day. They will stock there in batches of 200. Both of these methods are extremely competitive and only recommended for experienced restockers. You can also find the card through random events.

However, the more popular way to aquire A Mysterious Valentines Card is to buy it off the Trading Post, Auction Block, or Shop Wizard. Prices fluctuate greatly throughout the year and are dependant on the supply, demand, and nearness to February 14th. It can be as much as 500k when the hype of Valentines Day nears but the supply is low, to 100k when the demand is high as well as the supply, to the low 50k range a few months after Valentines Day when investers and hopefuls are no longer interested.
