Not wyckii they are almost never available where im at. And when they are they are never labled as asian red tail cats, plus they cost more. Asian red tails wyckioides are very common in my area ive owned a bunch over the years.
On the wyckii: yes, something appears to have changed dramatically in the last year or a few. IME and that of other hobbyists, small, cheap wyckii disappeared. Nowadays, they are larger and far, far more expensive. Like you said, $100+ for 6"-10".
IME, I believe the only nemurus we get are albino.
