That and the anti-pattern of using Amazon as a quasi-tool-rental outlet where they buy something for a project, use it, and then return it after the project is done. The 'borrowing' aspect was also an issue at Fry's in the Bay Area where test equipment that they sold would have been used already.

Of the two I think the 'borrowing' pattern to be pretty unscrupulous. I see the buy a bunch and return the ones you won't use/wear/eat what ever is more along the lines of the store fitting room approach.
