Hmmmm.... I have only been to one show (so I am no expert here), but when I was there, not many females were less than $100. THAT BEING SAID, I bought a male pinstripe hatchling for $80. The breeder was willing to negotiate it lower but after not seeing many pinstripes, and how expensive other morphs were, I just gave him the $80 - I believe it was worth it
I probably could have gotten my BP for around $60, so it might not be unheard of to find a female for $75. But you may want to ask for it to be sexed again to be sure.
Good luck!
