Popped into my local sunglass hut today and tried on a pair of Chanel sunglasses, £240!! wasnt going to buy them and probably never will, but the manager of the store told me that as they are the only supplier of sunglasses such as chanel, d&g etc (they supply them to john lewis and all airports etc) that all Sunglasses Hut's CAN remove airport tax of 15%!! he offered me the same pair of glasses for £204! Huge saving! If your thinking of getting some sunglasses from there, ask about the airport tax, i dont think the guy would have offered it to me if i hadnt of said they are abit expensive. Always worth trying!
