Card Prices in Different Stores

I know malls are typically more expensive, but I went into claire's yesterday with my friend and they had some Paradox Rift packs near all their Pokemon stuff, and they were $12.99 for one pack! We were both like jeez, who's gonna buy these? That's so expensive, for reference the packs at the Target near my house are like $4.99 at the most (probably similar around you), and they're like $2.99 or $3.99 at the five below. Stuff at the mall usually costs more, but that's like 4 times as much, have you seen stores selling cards for that much before?
