I have been member in the past however after getting into a car accident in their jam packed parking lot I decided the membership wasnt worth the hassle. Fast forward several years to now after calling Costco said you did not have to be a member to have your glasses done there. I drove all the way to Henderson braved the still crazy hard to park very dangerous parking lot only to go inside and be told that yes you do have to be a member. I don't know what the problem was but Costco sucks
