i think it's $14-$16 depending on tax. right now, they're quite rare so if you bump into one, you should buy no matter how much...as long as the price isn't to extreme...then it's not worth it.
I got mine yesterday! My dad was at Wal-Mart and I was at home with my mom and 2 sisters. My mom had to tell him where the toy aisle is, and where they would be, and how much they cost. He bought 3. That was about 42$ all together!
