I bought my rats from a locally owned pet store too but so far so great! The only problem were they weren't socialized very well but they're making progress!
I don't think it's a bad thing to get them from a pet store, if you're like me, I live in a small town with no rat breeders or shelters close. So I got them from my pet store and saved them from being eaten.
Anyways I hope you find this forum helpful, it's helped me a lot
