Customer Reviews
Easy shopping experience
I needed a new air fryer, and I saw they had one on their site. The whole process was pretty smooth. Found it quickly, added it to my cart, and checked out without any fuss. It arrived about four days later, which was decent. Works perfectly, cooked some chips in it last night. Happy with how easy it all was.
Always reliable for bulk items
I've been a Costco member for years, and I always come back for their bulk groceries. This time I ordered a large pack of toilet roll and bottled water. Like previous orders, everything was exactly as described and arrived on time. Their consistency is a big reason I keep renewing my membership. I know what to expect with their delivery times and product quality. Never had a bad experience with them.
Good deal on nappies
I was looking for a good price on nappies and found a bulk pack here. It saved me a decent amount compared to my local supermarket. The free delivery definitely made it worth it. I felt like I got good value for my money, which is what I always look for.
Decent TV, delivery took a while
I bought a new television during their electronics sale. The price was competitive, and the TV itself is great value for money. The picture quality is clear, and it was easy to set up. My main gripe was the delivery; it took 6 days to reach me in Edinburgh, which felt a bit long compared to some other online stores. Customer service was helpful when I called to check on the status, though. Packaging was good, no damage to the box or the TV. Overall, I'm happy with the purchase but wish delivery was a bit quicker.
Good quality, quick delivery
I ordered a Kirkland Signature mattress online last week. The website was pretty easy to navigate, found what I needed without much hassle. Delivery was faster than I expected, it got to my house in Manchester in about 3 days. The delivery guys were professional and even helped bring it inside. The mattress itself seems well-made, good support. I've had it for a few nights now and it's quite comfortable. I also grabbed some coffee beans and laundry detergent during the same order. They arrived in the same shipment, everything was packed securely. No issues with anything being damaged. Overall, a solid experience for a bulky item.
Costco Community Discussion
Share tips, ask questions & help fellow shoppers save more
Hey, thinking of getting a membership. Do I really need one to buy stuff online or can I just browse and checkout like normal?
Are those 'warehouse savings' coupons any good? Do they actually save you much or is it just like a few quid off?
Just wondering about delivery times. If I order a big appliance, like a washing machine, how long does it usually take to get to London?
What's their return policy like? Is it a hassle if you need to take something back, especially if it's a big item?
