You never know, you may have a reptile show local to you. I drive down to the one in Detroit every once in a while. Lots of nice breeders and I know their reputations well through forums like this or just word of mouth.
You may even have a breeder right by you, shipping does cost a little extra, but it's a lot of times worth it to have a healthy and chunky BP.
You may even decide to skip the normal and go for something fancy like a pastel or mojave!
