To clarify... Establish direct contact with breeders that can do it and have both genes in their collection. Be in touch. Keep close contact with breeders that could produce them, or are producing them, or have one.

You need to be on the waiting list when the female lays the clutch. Even better, the breeder needs to be aware of what you want when deciding which males to breed to which females.

And yes, i mean, the price is unknown because these snakes get sold so rarely, but the higher 4-digit numbers seem plausible. Albino pieds are i think the most traded visual double recessive, what does a visual albino pied go for? Here you can get real market quotes.

If you have the right connection at the right time and drink a beer with the right person, maybe you can get one for 1500 or 3000, if you are willing to wait for a few years. If you want one soon, then the number someone else threw in, 8000, is plausible.

Its high-end stuff, traded generally from breeder to breeder only, and you want in. Starting from scratch it requires a minimum of 2 generations and odds of 1/16 need to be beaten. (1 egg out of 16 eggs will show the double-recessive when breeding double het to double het).
