Sunglass Hut has signed an exclusive partnership with Macy's. The American department store chain will be the only one in the U.S. to host special Sunglass Hut counters. Conversely, Sunglass Hut, which is already present in 240 Macy's stores, will be the exclusive operatotr of the chain's in-store sunglass departments. The number of these counters at Macy's will rise by 430 to 670 between the spring of 2010 and the spring of 2011. A financial analyst estimated that the deal could boost Luxottica's annual retail revenues by more than €100 million.
