iTunes is the only music store seeing a significant boost to the number of purchases at its shop, online banking site Mint notes in a recent look at its own data. While those visiting Apple's music store have always bought more frequently, shopping about 2 to 2.5 times a month, the introduction of variable pricing in April has actually led to customers now buying an average of nearly 3.5 times a month as of July. In contrast, none of its competitors have ventured significantly past 1.5 visits.
