“I work for a cabinet manufacturing company and we looked everywhere for a certain screw to replace an item that was discontinued. Fastener Superstore was the only company that we could find that carried anything that would work for us. The customer service was fantastic and shipping was quick! We will definitely purchase again and highly recommend this company!”
“Our favorite ❤️ Costco location. Not quite as crazy as the one on rte 59 or Oakbrook although it is getting more and more popular. Friendly employees. Caveat They don’t seem to carry as much merchandise as the other two eg seasonal items”
“This Costco is spacious where even during the busiest hour you can get around easily. I’ve found that the employees at this location are more kind and courteous. Always a pleasure visiting this store.”
“Legit alternative to U Line. These guys have absolutely top notch customer support, good delivery terms, and their shipping materials are competitively priced with ULine. It's taken quite some time to find an alternative, but these guys are the real deal!”
“My favorite location, I love the people who’re welcoming. They are always nice, smiling and friendly. Products are great, and it’s a lot cleaner than other locations.”
“Costco gas station sets the gold standard for value and trust. Premium quality, unbeatable prices, and consistent excellence—everything is efficient, well-curated, and worth it. From everyday essentials to standout bulk finds, Costco delivers smart shopping, no compromises. Straight-up elite retail.”
“$4.88/gallon today, May 20, 2026! However, I remember well when I paid just $3.00 here in Bolingbrook the day before the zhit hit the fan. Looking forward to better days.”
“Cannot say enough fabulous things! Working with Yvonne and getting all future project guidance and materials here!
My partner and I recently spent an afternoon at ProSource looking for better options for an upcoming bathroom renovation. Everything from the big box stores was…..basic at best and tacky at worst. There was no design support, we were overwhelmed and lost.
But coming to ProSource and working with one of their sales associates Yvonne, we couldn’t be happier! She helped direct our vision to a new level, she helped consult to keep us in budget but elevate this project from something we were dreading to something we can’t wait to see executed!”

“It very much sucks that you can't shop at Costco unless your name is on the membership card but nonetheless, it's still a good location! I tried out the strawberry sundae with chocolate syrup and it was super tasty and had great value ($3). The service here is also quick at both the food court and the regular grocery store self checkout lines.”
“Costco in Bolingbrook...what is not to like? Costco is great for providing bulk purchases at a reasonable discount and provides a nice clean environment to shop in. We're from southern Illinois but ended shopping here. Chicago is crazy expensive compared to the southern part where freedom is cherished and Costco helps ease the pain of the Chicago expensive experience.”

“Regarding the Costco Tire Center @ Bloomingdale. Josh P and his team did a TREMENDOUS job with our Audi Q8. We are very happy we came to the Bloomingdale Costco for new tires. The customer service and attention to detail was much better than anywhere else I've been. It is also great that Costco has free air to Costco members, I didn't know that until now.”
“Costco Pharmacy went out of their way to get my diabetic supplies I needed. They made every effort to get the correct needles on-time contacting Dr/Nurse for me which I had left messages for. I really appreciated that because I was almost out. Just wanted to say they make sure to let you know! Easy to talk to and pick-up in store or delivery.”

“Costco Warehouse in Naperville is a classic Costco win - clean, well-organized, and dangerously good for your wallet (because you will buy more than planned). The staff is friendly and efficient, checkout moves fast even during peak hours, and the inventory is well-stocked with everything from groceries to those “how did this end up in my cart?” impulse buys. Gas station lines can get busy, but the savings make it worth the wait. Overall, reliable, convenient, and a solid 5-star stop for bulk lovers and free-sample hunters alike.”
“Standard Costco with good selection. Food court is nice. I recently got the pepperoni pizza, chicken bake and hot dog. The hot dog and chicken bake were great. However, the pizza quality seems to have gone down hill but was still good. All in all, a nice Costco option in the area.”
“Was able to schedule an appointment the very next day for new tires, as they were the only ones near me that had them in stock. They were considerably less than other estimates I had received and I was in and out in under 30 minutes. Super nice guys running the shop and discovered the offer free, balancing and rotations if you buy their tires.”
“Always crowded no matter what day I go.
This is a dangerous place to go to because they're emptying my pocket every time.
My family will not be happy if I don't go groceries shopping here. We're so hooked.
We love their precooked dinner like lasagna, meatloaf, chicken pasta, salmon seafood stuffing and many more...
My pets foodd and supplies were also purchased here. Not to mention the all seasons decorating, flowers, plants, medicines, and even jewelry.
As long as you can afford it, Costco have it all.”

“Great location. Clean store. Very helpful staff. Tasty samples.
I can’t say enough good things about this location and the staff.
Lots of parking even on busy days.
Getting gas is a breeze as well.”
“Costco's Oak Brook, IL location provided wonderful quality service and results! Kathryn and Steven are truly distinctive in their caring, service excellence and tailoring to a customer's needs. Very cost effective also. They have helped my dad, my mom and me in the last 5 years, and just last week I once again was in for help, and was delighted! Highly recommended!”

“It’s cold outside (imagine that, in Chicago) get in my car and tire pressure is low on all 4 tires, exceptionally low on one. Costco took my car in right away and ended up finding a nail in one, they quickly fixed it, checked all of the tires and just aired those up and sent me on my way.
We really appreciate the service we always receive from Costco Tire, fair prices and convenient hours.”
“Costco is the best! Always well thought out, organized, excellent quality, great prices, fresh and delicious food, and very courteous knowledgeable and helpful staff!!”

“Elias was absolutely amazing and on point. One of our guys rolled up with the tire pressure light blinking. He Immediately topped off all the tires and pulled out a wireless meter to diagnose the front right sensor was busted. Without parking, he took the car right in and within 15 minutes the car was good to go, all at Costco’s discounted rates. No appointment, In-N-Out 15 minutes and just $64 later.”
“Great store in chicago, in all aspects, regarding food,safety ,customer service, employees helping customers, very good delivery services,sometimes shortage of items in aisles due to some reasons, but overall performance of cashiers trainees also good.”
“I've been going here for about 5 years I think. The staff is great and the doctors have always been professional and thorough. I frankly don't understand all of the bad reviews. I've always had great experiences here.”
“These guys make it right everytime, even when the problem isn’t in their hands. Had packages get lost with overnight shipping and they’re always quick to send another out to assure we keep the ball rolling in the shop. Couldn’t be more grateful for this team. They send out same day every time, extremely easy to get a hold of someone to talk to, and very helpful over the phone as well. If you’re looking for a reliable supplier these guys are it!”
