What is he testing? He is not, for example, testing if people would pay $50 because I'd assume 99.99% of people who would pay $50 will instead pay $25 whilst that is an option.

I didn't say it was a good test. Actually I sent him an email about it as soon as I saw it. Never-the-less, I still don't think that it makes any sense that people are acting like whiney babies because Andrew is trying new things.
