Don’t go here if you don’t have an appointment. They do not care if you have an emergency or a place to get to. They will not fix your tie quickly and get you on the road.

I made an appointment online to bring my car in for tires rotation and re-balancing but had to wait for 2 hours to have the service completed. They were running behind but did not notify me until I arrived. The check-in staff was friendly and apologetic. There was no issue with the tire rotation. I hope this negative review will let Costco Service Management know that 2 hours service with appointment for tire rotation is a bit excessive. They should have a system in place to notify their customers via text or email when they are running behind.

Made an appointment for 11:30 and they took my keys and told me it would be an hour and a half. I couldn't do anything including shopping because I had no where to put the stuff I purchased so I waited at the nearby coffee shop killing time on my phone. At 13:30, I get a call saying they wanted to replace tire pressure sensors and it would be ready in another 20 to 45 minutes even without replacing the sensors. might as well just wait 4-5 hours as a walk-in if appointments take 3 hours.

The prices of their traditional Car & SUV batteries are quite competitive. Do yourself a favor by bringing in your used-up (dead) battery so that you never have to pay the $15 or $20 core charge. I'm not really sure about 2018 and earlier - - but Costco employees are not obliged to remove nor replace your battery (under the hood) that labor is the customer's task.

People that make a big deal and freak out of random rare experiences need to get a life. They swear that Costco isn't a incredible place to shop or that they won't take the time to make things right. People let's have some patience and understanding. It's not the end of the world. These people don't understand how hard it is to be a successful business and things ain't always go like one wants my experiences at almost all Costcos are always the same. Get in.. get out. Stand in line... listen to all the workers and customers. Overall your lucky to have somewhere to get products in bulk and at a reasonable price. Pay for the executive membership if your there once a week. It'll pay for itself. Yeah workers won't always be the most courteous but they have to deal with people like the ones who are just looking for any flaw.. to feel special and needed so they have to let everyone know their "horrible" experience... lighten the fuck up. Be open, calm and thoughtful of these people. We all have issues and bringing them down to 1 f*%&in star isn't helping anyone. Either way people don't really give a shit about your reviews or thoughts. They'll always be there no matter what your opinion is. So be kind and understanding and you'll have a better experience almost all the time. This place is only for true connesours of the ultimate hands on shopping experience. Hey you have a problem when them shop online and save yourselves the trouble of thinking anyone gives a shit about what you have to say.

DO NOT BUY YOUR XMAS TREE AT COSTCO Bought Christmas trees from Costco San Dimas for many years.Xmas tree roulette! We buy it all tied up and reveal it at home. Always had great results. 7-8 ft for $49.99. Excellent value But now, we went today, 11/26 to get our tree. Very disappointing, the only trees they had were 5-6 ft for $49.99, bad value Not happy but we were there and we purchased the tree.This tree was so pathetic we had to go to Home Depot to buy a smaller tree stand.I'd take it back but it is not worth the time and money.Not a good Costco purchase.

Crowded on the weekends, so if you are looking to get in and get out, definitely try shopping during the week. This location tends to have fully stocked shelves which is nice very friendly workers. There is ample parking but again on the weekends you will be circling and circling and looking for a spot.

Went here to replace a popped tire since it was the closet place to me. They not only took the job but said to replace all of them. Thus it causing their employees to be Angry and causing damages to my vehicle since they were already closing! DO NOT COME HERE AT ALL.

Optometry department was SUPER slow today. Have been here nearly 30 minutes and they only called 1 number. A lot of standing around. Started off with 3 stars but the longer I wait the more stars I remove.

I was super excited when my dad gifted me a memebership for my birthday, however after visiting Costco for the first time, I will never return, due the unprofessionalism and disrespect from Alexandria, the clerk who checked us out at this location. My fiancé and I had the afternoon off so we went to this location to check it out and stock our fridge. We went to check out and my fiancé put in our household card and the clerk freaked out and demanded to see his membership. I calmly explained that we were paying using a household account and that I did not know it would be an issue. What I presume was a supervisor stepped in and explained that he would need to present his own memship card in the future but said they would let him pay this time. My fiancé and I then began talking amongst outselves and at the end of our conversation said to him "it's fine, we will just use our Sam's Club" when the clerk popped off and said "that's fine, go there," with an attitude turned up to 100. Stunned I repeated "that's fine?" Her supervisor equally alarmed by her attitude apologized and leaned over to the clerk to tell her that she shouldn't say that. The rudeness did not stop there, once the transaction concluded, she shoved the receipt in my face nearly hitting me and said "here!" I fully understand that they have a policy however as a first time guest I was simply not fully aware of what it was. Full stop I'm not going to pay $120 a year to shop somewhere to be treated like trash or less than. There is a polite and professional way to deal with customers and Alexandria clearly needs more training as well as a serious attitude adjustment -- and it was a big disappointment considering how excited I was to finally be able to shop here. In conclusion, we will not be returning to Costco, we will stick to Sam's Club where I've always been treated with respect and dignity while shopping.

Shopping at this Costco is always a fun experience. The hot dogs and pizza are always a nice treat and reward for arduously pushing a shopping cart with a load of products including cases of water. I'm always checking my Fitbit to see if the effort puts me in "fat burning" mode. Hehehe I have been a regular customer since the days when it was called Price Club. The customer service is mostly great, and I get to return defective items without any resistance. I have even used my Costco membership to get a discount when purchasing a car. Finding my exact size in the men's clothing selection is always an adventure, like looking for treasure without a map or an easter egg hunt. When I do find my size, I want to let out a victory scream and dance like I won the lottery but then I quickly realize it's only a pair of $16 shorts and a scream is not entirely warranted. I usually am able to find parking in my favorite "go to" section and eating my $1.50 hot dog as I drive home is "priceless."

It's a Costco. You know what a Costco is. This one is less crowded than some (Azusa) but it's rare to see short checkout lines.The pharmacy has very good prices on prescription medicines, sometimes beating the pharmacy chains by a factor of 20! I am not exaggerating. That's the main reason we are members.

This is my favorite Costco by far. The layout's great and product selection fits our needs. Every once in a while we have to go to a different location for something specific (usually dog food or flea medicine), but nine times out of ten, it's here. I hesitate giving a five star rating because I don't want to encourage extra traffic... but they deserve all the stars. And thank you to all the receipt checkers who draw smiley faces!

Walked in for tire rotation at 1015 this morning and was turned away by an obnoxious female clerk. I asked about appointments and was met with an eye roll and shoulder shrug. You need to do better Costco! We usually have good service at the San Dimas Costco, but today it was horrible.
