Just thought I’d share my experience with cosme-de… I actually ordered off their ebay page just to be on the safe side.
Anyway, I ordered a NARS blush for $34 which I think is a great price. I ordered in early January, a few days later they emailed me to say they didn’t have any in stock but they would be getting new stock mid Jan so I had the option to cancel if I wanted. I said I would be happy to wait. I got my order today (about two weeks later), I couldn’t be more pleased with it. Everything was well packaged, the blush is genuine (I believe) and fresh. They also threw in an Avene cold cream sample.
Overall I’m very happy with their service and would recommend them!
