Is the Disney Up Valentine's Day plush set no longer at Disney Store?

[DodgerGirl]

My mom wants to buy the Disney's Up Valentine's Day plush set but I have never seen it on clearance at Disney Store and so I'm curious to know if it's no longer sold at Disney Store anymore? I was at Disney Store and didn't see it listed anywhere and the only Up plushies they had was of Dug the dog and Russell. Is this set considered rare and did Disney not make very many of them?
