I've seen hets sold as normals, but the one's I've seen it done with is the males. An '11 het albino male or even an '11 het pied male really isn't that much in demand seeing as the visuals are being produced often enough to make them affordable.
I've seen 50% PH albino females for as little as 50 bucks. So if that girl is het for anything I'm thinking she's more than likely PH albino or pied, ghost, off chance PH clown--one of the recessive morphs that has been around long enough that the visuals and 100% hets are now more reasonably priced.
Regardless, she's a nice looking snake and getting a nicer than average normal at the right price isn't all that shabby and she still gives you some good breeding possibilities with codom and dominate morphs even if she never proves out het for anything.
Het females are never sold as normals! PH females are just normals until proven so they are often sold as normals! $25 is a good price for a normal female regardless!
