would it be better to start off selling at cost or lowest acceptable margin and increasing price? having an extended period of time early on with low sales could be pretty harmful, no?
But, it's a very good question about starting high or low. The common wisdom is to always price high and then move lower. I've seen this work well for sales by being able to offer a discount to close a deal. There's also the perception that expensive = high quality. The only real way to know for sure, however, would be to duplicate the test and go high-to-low on one and low-to-high on the other.
