Club memberships Nonmembers of Costco and Sam's Club often wonder if the $45 to $50 membership is worth it. I always say that it is, and here's an example to prove it. I recently took my current eyeglasses frame to Costco's optical department for new lenses. My optometrist wanted more than $400 for high-index, progressive lenses with anti-reflective coating. Costco charged me $191. Highly rated by Consumer Reports, Costco does good work. I was warned by the local technician that the lab may not accept non-Costco frames if they're not in good condition. (Costco charges $18 if you bring your own frame.)
