Been looking at replacement lenses for my Oakleys. They offer aftermarket ones for a whole heap of other brands although I've never tried them before. They've been reviewed at Oakley Forums and seem decent.
The promo code is advertised on their Facebook page stating it's for their Diamond Bio range but I tried it on the Ultra range and also works as well (as I wanted mirrored finish). The Edge range doesn't seem to work but if you have a Diamond or Ultra lens in your cart, it will apply 25% off the whole cart. Free shipping also.
What's wrong with the original lenses?
