Any question answered...

Where is the cheapest place to buy genuine Rayban Wayfarers with polarised lenses? Cheapest so far is about £150 from asos - I remember these used to be like £80!

Shuron is my standard answer - I know they're not Ray Bans, but I bet they made them first, still make them at their original location and the quality remains high. You can also spec an entire range of customization (depending on the model) from arm length/style to lens size to bridge width to colour or material.
