I didn't use the Costco Optometry department but did visit the Sunset Vision office (their doctor's office) for my vision test as well as the family. Without an appointment on a Saturday afternoon it was about a forty minute wait while a Sunday morning appointment had me in and out in 30 minutes. Everyone was polite and professional and the process was simple for a moderate price. Waiting for the Costco Optometry services was actually a longer wait! Definitely recommended.
