I found local shop that has the GP4000S II in stock. $69. a new one off Amazon prime with free shipping is $34! I could order TWO and swap out both my tires if I wanted....

has anyone had a problem with getting imitation tires off Amazon instead of the real stuff? I have seen a few threads where people have bought either bike tubes, shimano pedals, or other bike specific items from Ebay, the items were packaged as genuine, but what showed up was clearly substandard and made in china...

is $69 a total rip off?
am I ok to just order these off Amazon and save a few bucks?
