I'm increasingly convinced the view counters for shop items are busted... There seems to be such a consistent pattern where the listings I have assigned to shop categories show 0 views whereas the ones not yet placed in my shop show several... If you look at the following screenshot you will see the same item, listed at the same price (accidentally listed twice in fact, I am just about to remove the duplicate listing), the shop items show 0 views, the non-shop one shows 8... This is pretty much the case across all my items, the vast majority show 0 views but any not yet assigned to to the shop show several. Having said that it's hard to assess as my non-music items tend to attract much more interest here...
I am going to try an objective test soon, I will ask a volunteer to view some listings with 0 views and see if the hits register, will report back soon
