Bay Area reptiles--Ray

Hi, all. I want to purchase 2 axanthic BTS from Bay Area Reptiles. I have asked for a guarantee that the skinks stay axanthic, after their next shed. When asking Ray if he had seen the skinks shed (asked twice. I asked so he could verify to me, that the skinks did indeed stay axanthic after shedding since he stated he had had them for 3 or 4 months) he never answered.
Can someone tell me if they have dealt with these guys before? Ray has been polite and courteous, etc but I don't want to spend twice the money on animals that might shed out a normal color...........So-any experience with them, or a BTS that has shed out to a normal color?
They are listed on Kingsnake.

I've gotten a few animals from Ray over the last few years and they've always been in perfect health. He's extremely knowledgeable and I would not think twice about buying from him.
