After shopping around online i found OpticsPlanet.com and ordered my Ray-Ban Daddy-o Prescription Sunglasses model# RB2015. i received them as ordered in 2 weeks and the Rx was perfect! I live in Puerto Rico so ordering from the US can be a problem sometimes, but not with Optics.planet.com.
Pros: lowest and fast delivery
Cons: Rx prescription sunglasses are still expensive
