'Average' is certainly used more often than 'mean'. A "mean price" sounds nasty (or especially good in some slang), and I doubt if the average person would be sure about the meaning of "the mean price". At least where I come from, it's a mathematical term, and the average (mean?) person would not be able to tell you the difference between the mean, the median and the modal price.
