I have a fetish for designer sunglasses. I was happy to find a sight that could save me some $. Ordered my Prada glasses Tuesday, May 15th before 12pm EST, and received them Friday, May 18th before 12pm EST. I have no questions in regards to authenticity. This is not my first pair of Prada glasses. Customer service was outstanding. Email replies were very timely. I will definitely shop Luxoneyes in the future.
