1. [R2] 5/5 · US Shopping for Area Rugs: Costco had a great selection of indoor and outdoor rugs. The sizes of the rugs were perfectly described so I could expect them to fit nicely in my patio areas and kitchen. Nice features to know that shipping and handling were included!
2. [R16] 5/5 · US Easy navigation: You can find all discount thru Costco app
3. [R27] 5/5 · US Great new products: Love the app they are always updating it with new inventory
4. [R52] 5/5 · CA Costco App: I’ve had a great experience using the Costco app. It’s very user-friendly and makes shopping quick and convenient. Browsing products, placing an order, and completing payment with both my Costco membership card and credit card is simple and straightforward. I also appreciate the delivery updates, the app keeps me informed with notifications when my package is on its way and about to arr
5. [R23] 5/5 · US Delivery Too: Time, travel and money savings! Costco is the best!
6. [R24] 5/5 · US Great APP: Just purchased multiple items via the app and everything was nice and easy to complete my purchases
7. [R79] 5/5 · CA Always get what ya need.: Online ordering helps my families life run much smoother!
8. [R4] 5/5 · US Customer Service: Customer service was very helpful and patient with me and solved my ordering issue.
9. [R1] 1/5 · US One of the worst apps ; best stores: The app is pathetic when compared to Amazon or any other half decent E-commerce site. Log in is hard. Loses credentials constantly. Loses cart. The UI is from the 1990s. The team working on Costco app needs new thinking. New leadership.
10. [R12] 2/5 · US Horrible App: The mobile app is horrible. I’ve been a Costco member for years. I can’t login unless I add a passkey which is beyond frustrating. I just want to login using my username and password!! The passkey continuously pops up and it doesn’t allow me to login.
11. [R37] 1/5 · US Unbearable Passkey Prompt: The app keeps prompting a passkey pop up every few seconds. There is no way to disable or delete this. I even tried disabling passkey in my iPhone settings and the app still relentlessly keeps asking for it. It’s built into the app with no way to disable it, yet when I try to create a passkey, it only gives me 2 options that aren’t possible. Like I’m supposed to have a k
12. [R43] 1/5 · US Slow, logs out, no Apple wallet: The app is slow and laggy. It constantly logs me out, which is very annoying and unnecessary. Lack of Apple wallet support is very disappointing and outdated. They use a rolling QR code to combat card sharing, and people who follow the rules get lumped in with the cheaters and miss out on having a good app with good features. The app shows as five stars, but if yo
13. [R17] 3/5 · US I love Costco but this app not: I love Costco and their physical stores but this app needs a bit more work on keeping it loading faster and more seamless.
14. [R21] 1/5 · US Slow: Hardly loads
15. [R40] 2/5 · US What’s going on with this app: In 2026, no excuse for a shopping app to be as slow as this app (adding items, updating cart, browsing, etc.). Data Product side should prioritize overall shopping experience by comparing Costco’s app with other apps like Amazon, Walmart, etc. Tons of movement needs to take place here to make this app better.
16. [R3] 1/5 · US Access Denied: Try to order on APP it couldn’t add to cart. Go to cart page it said access denied. Hope they will fix this issue soon
17. [R15] 1/5 · US Unable to access Cart on the app: Could not complete the purchase as once item is added. The cart page is not accessible, it says Access Denied
18. [R34] 1/5 · US Nothing loads now: Can’t review prior purchases on the account tab. Can’t get the cart to load for me to check out. Really not sure what you can use the app for anymore to be honest.
19. [R69] 1/5 · CA can't review carts: After new version installed, after add items in the cart, can’t review it, and keeps saying access denied.
20. [R9] 3/5 · US Apple wallet: Would be nice to access my Costco ID through my Apple wallet
21. [R38] 3/5 · US Make it available on Apple watch: Make the QR code available on Apple Watch please so I can just scan that to enter store!
22. [R62] 3/5 · CA Apple Wallet Support!: Please add Apple Wallet support. This would make things so much easier to customers.
23. [R41] 3/5 · US UI appeal & response time can be much better: UI looks old fashioned, response time has improved a lot but also can be much better.
24. [R44] 3/5 · US Bad UI: Really bad UI. Was incredibly difficult to update my address and check out for a $50 item, multiple errors, etc.
25. [R46] 2/5 · US Pretty rough: Outdated underperforming app.
26. [R30] 2/5 · US Orders not loading …: The feature that is meant to list your online orders has stopped working. Still getting emails about my order but this important and basic function stalls out. Just says “Loading…”
27. [R31] 1/5 · US Can’t get a printable receipt or invoice: Doesn’t have the ability to create a printable receipt or invoice for online orders. This complicates insurance and FSA claims.
28. [R36] 1/5 · US Awful App: Basic functions such as reviewing your orders takes ages to load , completely unintuitive pathing to connect with customer service. The app is overall clunky.
29. [R8] 1/5 · US Useless App: 9/10 you open the app it doesn’t work
30. [R63] 1/5 · CA Garbage: Nothing loads. Most screens are blank. How does such a big corporation put out such a garbage app that doesn’t work? Gets worse after every update. You’ve fixed nothing in 6 months.
31. [R65] 1/5 · CA User experience: Terrible user experience. Cannot shop or purchase anything as the lists do not load.
32. [R73] 1/5 · CA App is consistently unreliable: Search results or pages you click through are endlessly caught on loading. This is through multiple iterations of the app and after uninstalling/reinstalling.
33. [R19] 1/5 · US Please update: With the new update it made it harder for me to add coupon savings to my list. Once I click the “heart” button to add to my list the page updates to random category. When clicking on category on top is no help, it’ll just bring you to a random page. Very frustrating.
34. [R20] 1/5 · US Warehouse Sale started today (6/15/26) but when adding to a list, sale items are shown as Expired???: Fix the app and allow Chat for app issues. Defaults to warehouse only.
35. [R42] 1/5 · US How does this app keep getting worse?!: Now I can’t even find the items advertised in the circular
36. [R48] 2/5 · US BRING BACK WAREHOUSE SAVINGS TAB: Please bring back that tab. So disappointing it keeps disappearing. Shame!!!
37. [R49] 3/5 · US Cart is slow to respond to changes: I don’t like how slow the cart it to respond to changes but in general the app works pretty well
38. [R28] 1/5 · US Great store, Terrible app: As much as we shop at Costco with our weekly trips to feed our family, the app is probably the worst out of all the retailers we use. Some items are literally impossible to search for in the app, and they aren't even seasonal items, but regular items that we see are carried year round. Costco, you are a great place, but at your size, there is no excuse for not having
39. [R59] 1/5 · CA Takes 1 day let you know order is canceled: 1. due to inventory out 2. Wrong billing address for bank 3. oh now we don’t have the new billing addess on your costco account back to back. + plus have to call them everything to get the voucher again , since the order got cancelled Such a bad service! very disappointed online service don’t wanna compare with amazon but yeahh!
