We don't see much data out there on the sales figures of Apple Stores. But a Barron's article (via Seeking Alpha) quotes an analyst saying that same-store sales at the computer giant's 250 stores dropped 17.4% year over year in December.We find this odd, considering that in its latest quarter, Apple posted record revenues and profits. It seems they sold more computers, iPods and iPhones than ever.So what's going on here?The article says that traffic at the stores was only down 1.8% Are people just going into these ultra cool stores just for the experience and not purchasing anything? Were Apple's stores just intended as marketing vehicles in the first place?Maybe people are just buying Apple's products at other retail outlets where things are lower priced.
