I've been wearing Tifosi Envy for a year now and I love them! I just ordered the Quam 1.5 in pink to go with my new bike, but I still love my Envy's. I've really beaten them up pretty good and they still look new. The lenses are easy to change and the three I have really cover all the conditions I've ridden in so far. I even coated the clear ones with RainX and they rock!

I know you said you have a coupon, but for anyone else considering Tifosi, I highly recommend Athleticshades.com. I ordered mine there...same price as my LBS, but no shipping cost and no tax. They also shipped the same day I ordered them! Of course, you'll want to try styles on in a shop, but then pick what you like and get them online.
