Sunglass Express hides specific "terms and conditions" for returns & exchanges (15% restocking fee, inconsistent specifications from what is stated online & delivery invoice, etc.).  Product description-sizes, colors, etc. not clear/accurate. You MUST see RayBan official website to decipher what product you are purchasing and you will notice that you may only be saving $1.00 if anything at all!  Although I followed all requirements, didn't receive requested response confirming my credit was issued.  Will never purchase from Sunglass Express again!
