If you don't care the quality of pastel, you can get one for a rather low price.

If, however, you plan to breed, and want to produce quality pastels, then be willing to pay more.

I only purchase the best examples that I can find of any animal (including normals) and am willing to pay more for quality.

Conversely, any Grade A offspring that I produce will be sold for more than the average cost. There is a market for people looking for only the best and who are willing to pay more for the best.
