I'm getting some new sunglasses, and found a pair from Carrera that I liked. I was told I could get around 20% off the MSRP since we're such good customers, and I'm just wondering if they're worth it quality wise. It's basically the Carreras or perhaps some Ray-Bans that I liked, they did have som Gucci, Dior et al, but they didn't fit at all. Not a big store, and I could use some new sunglasses now. So, are Carrera at 20% off worth it or not?
