IMO i wouldnt pay more $500-$600 for her. Shes not quite to breeding size and shes a live mice eater. That means if youre buying from the pet store she probably needs like at least 4 a week. At my pet store mice are $2.30 so thats almost $10 a week to keep her. I would pass on her personally. If theres anything more you can try to do to convert her over to at least f/t, preferably rats, then i would try that. Because then asking $700 for her would be completely resonable. Btw i hope you dont take this like im trying to insult you or your snake lol, im just explaining my opinion
