I think the logic does make sense, or at least makes money. I have a friend in an unrelated industry (sold hair related products) and had 3 websites with exactly the same offerings. He put the prices at 3 different levels and each site sold the same thing. The most expensive one actually brought in the most sales too. Weird. But it was valuable market research.

I think the same can be said for this situation. The internet makes it very easy to test what is effective. Different offerings, different pricing packages, etc. and you can do them all at the same time.
