You have to get your post count up and wait 2 weeks before you can access the exchange areas to buy lenses from him.Am I extra dumb? I can't figure out how to PM him?
Be careful. Some lenses that are etched are not genuine Oakley. There's a guy from the UK here who was selling etched Chinese made lenses (which some thought were Chinese knockoffs), but which he said were made by Carl Zeiss.
