The Picture that you have posted does look to be a Woma.
It is a Co-dom morph, so if bred to a normal the odds would be 50% womas and 50% normals for the offspring.
There is a Super (Homozygous) form called the "Pearl" but it appears to be a lethal gene and all the Pearl offspring have failed to live as far as I know. Though I would not let that keep me from getting a woma they do make some nice combos and are beautiful reduced pattern animals even in the plain Heterozyous form!
The link above to NERD does have some good information on the woma's and possible combos.
$150 is a great price for a woma, I personally would purchase a nice woma for that price.
