Query: Tamagotchi's Rule!

Seven of my friends have Tamagotchi's. They are really fun to play, and they teach you some responsibility. This might prepare kids for owning their own pet. I really want one, only every where I go they are either discontinued or sold out. I think they should have LOTS of them stocked in stores. I was really disappointed when Toys r Us siad they were all gone. One more thing. i think the Tamagotchi's should cost less.
