I had another wonderful experience at the Costco in Lake Grove, NY. I like change up my look with new eyeglasses every 18 months! The optician Alan was so patient in helping me select new frames…They have updated the entire optical department which I feel is now so much more personal, user-friendly and professional. I’ve only been using this Costco for all my optical needs, and highly recommend it. Kudos to Alan and his entire team!

Revision: Had a good experience recently with two new optical technicians, Sharon and Jorge — both were professional and helpful. I am raising a star for the place thanks to them!
I have to agree with others who mentioned poor service — Sandy was rude, and her manager wasn’t much better. Beyond the attitude, their lack of expertise in properly setting the segment height for progressive lenses led to multiple issues. They also charged for premium features like edge polish and ultra-high index lenses, but the results didn’t match what was paid/promised.
On several occasions, we had to get the glasses redone at a different Costco location just to get them right. Instead of taking accountability, they get angry at us because we went elsewhere to fix the problems. Overall, a frustrating and disappointing experience.
During a recent visit, we noticed some new faces but weren’t sure if there had been a management change. Hopefully things are improving — it would be much more convenient not to have to travel a long distance to correct the mistakes made by the Nesconset Vision Center.

Sandra was extremely rude, hostile and aggressive towards my mother and I. She snapped and yelled at me when I told her that I can get Warby Parker frames for almost half the price of the Nike frames she was trying to sell me. She aggressively up sold us and the final price came to about $365 for prescription eyeglasses and sunglasses. Also, I was able to use my insurance for the Warby Parker lenses saving me $60. Sandra didn’t even ask about insurance. At the end of her failed sale Sandra raised her voice and shouted at my mother and I - “GO ACROSS THE STREET TO WARBY PARKER AND SEE WHAT HAPPENS”. I saved $200 going through Warby Parker. I felt threatened by Sandra and the rest of our day was ruined. Avoid this Costco Vision Center at all costs. Sandra will try to rip you off and when you don’t buy from her she’ll get upset and shout aggressively.

Don't waste your time, I have gone twice to get my glasses done and they are rude, they have not been friendly at all. Both times I felt uncomfortable. I'm not coming back anymore. ??

Can't beat the quality selection of goods and healthy produce that is always fresh. Seafood and meats are outstanding, better than small shops both in price and quality. Kirkland brand is an additional bonus when cost matters. Costco stands by its products with an 100 percent money back guarantee, that is matched by no one!!!

Costco always has great deals (with monthly promos as well.) They stock a large selection of produce, frozen goods, raw meats and fishes, beverages (including beer,) household items/cleaning supplies, bakery goods, seasonal holiday finds and pharmacy items. This location can get pretty busy at times but they have plenty of welcoming staff to keep the lines moving. My must-have, favorite item to purchase is the Kirkland protein bars! Cannot live without. They come in cookies and cream, peanut butter, brownie, and chocolate chip cookie dough flavors.

I've been shopping at Costco since they began as Price Club many years ago. I've always been very happy with the selection and service. I recently went to the audiology department for a test and hearing aids. Yvonne, the audiologist I used, was very professional and knowledgeable. I'm thrilled to be hearing properly again. Everyone was very nice. I highly recommend using them.

Who doesn't love Costco??? From the premade food to the awesome prices on things like Nutella and time foil this place never disappoints. I love the executive membership where I get my rebate check annually. It pays for itself and then some.

I've gone twice for new glasses, employees there are always helpful and nice. Fair prices for glasses but selection is a bit small.

For the love of everything good in this world if you would like to have a nice, decent day DO NOT let the cashier Margaret check you out if you come here. That woman had severe anger issues and enjoys making other people's life's miserable because she very apparently hates her own. Will purposely crush your bread, fruit, and eggs like she did to mine because she didn't like the "amount of items that I had". Apparently her job as a cashier didn't have the description that she will have to ring costumers items up when helping them.....?
