I work for luxottica and one of the luxottica owned shops there should carry it. Where I am the lens crafters have it and the two sunglass huts (which I work for) don't, although we can finess them into the store if needed.
To the poster above: you're right not all will. There are different types of sunglass huts that sit in categories like Fashion 1,2,x and I think another is sport along with ones that carry watches too (not a watch station). Some glasses from more exclusive designers/brands are only put in one lux store in a zip code so you may find like in my area lens crafters have ferragamo, persol, chanel, dolce & gabbana (and d&g), prada, versace, while the sunglass huts have only prada, versace, d&g, and some others.
