BUYING/ORDERING PIRAHNAS?

I want to get a different species of p besides the common rbp u usually find in pet shops? Anyone from PA or the tri-state area that could tell me where to go? I am to the site and whole the p hobbyist thing. I checked the site and they told me they're was a pet shop in YORK, PA that sold some p's ... any feedback would be greatly appreciated! nice to meet everyone!!!
