Hah, crazy. Not you, them; the going price online is between $1-$2 per cherry shrimp, from what I've seen.
When I was in St. Louis, the only store that carried cherries charged $7.99 each. It's a bit better here in the DC area, but only a little bit, because my LFS still charges $3.99 per cherry.
Buy online. Try Swap n' Shop, I've had nothing but good experiences.
Even if it's crystal reds they've got, $14.99 is expensive unless it's one of the high-grade shrimps, like rich815 said. You can get decent-quality C grade fellows around here for about $3 each, it's not bad at all.
