I’ve been looking at the Turbines for a while, and I saw that the Turbine in Prizm Polarized is 30% off. When I add it to my cart it shows $144. Then when I go to my cart it shows 30% off (around $62), but when I look at the price it shows $164, which is only 20% off. It doesn’t correct itself anywhere along the the checkout process, so I’m holding off on the purchase. While I could get the them for 30% off on Amazon, I prefer to buy through Oakley with the better return policy and reduced risk of getting fakes. Has anyone else ran into this error?
