Albino Boas now run about $500-$700+ for your average Albino Boa. Then depending on the quality, line, size, age, color, etc, etc. they can run as high as $1200-$1800.
$850 isn't bad at all considering he has some nice colors, pattern, etc. The ones you see for $500 are plain and usually end up looking like large bananas.
the prices range sooo much and we were looking for one that wouldnt lose all its pattern as it grew up, we of course dont know for sure what he will be like but we are hoping he keeps most pattern especially in his pretty tail.
