there's a guy on W.32d street off fifth that has Bose stuff for sale from the trunk of his '73 Impala- and great prices- if you don't mind that they are made in Shenzhen
otherwise pay retail and respect the brands intellectual property rights
or shlep out to Riverhead and go to the Bose factory outlet- they have refurbs (genuine) at a discount
but is it worth at least a 2-hour drive each way? (unless you are going to the Hamptons- its on the way- sort of)
