Pastels are pretty common and look like they are settling down into a price for something just above a *nice normal.* Which is totally OK...really bright yellow pastels should sell easy to buyers looking for outstanding looking ball pythons. Once prices dip into pet range, not everyone and their brother buying them will actually breed them, so the supply shouldn't continue to increase at the rate it has over the past couple of years. I wouldn't in the least be suprised to see a good looking $150 male pastel next summer.
I think there will be a huge demand for pastels in the $100-200 range...
