In June we went to the duty free shop located on the pier in Phillipsburg. They have a Hot Look store inside. They have a very large selection of various brands. We got a pair of polarized Maui Jim's ($279) and polarized Costa ($259). They had a special deal, if you bought 2 pair you got a free pair of Ray Bans (not polarized). We didn't really try to negotiate on price but we saved by not paying taxes. Over the years, we have purchased from the Sunglass Hut on Front street many times. They sold Revo and they are the best but I can't find them anymore.
