I bought a pack of Turkish bread and some potatoes that looked fine on the shelf, but when I opened them, the bread was mouldy and the potatoes had gone green. I couldn’t use either for dinner and just wanted to return them for something fresh. It really made me second-guess the quality checks at Costco. - Sofie

I picked up a Bref toilet bowl freshener from Costco, but it didn’t work at all — no fragrance, no cleaning. It felt like I’d just wasted money on something useless. I went back hoping they’d take it back and refund me since it clearly wasn’t doing what it promised. - Michael

We bought lamb shanks that were well within the use-by date, but when we opened the pack, the smell was awful. For $22, I expected them to be fine, not off. All we wanted was to return them and get our money back for something we couldn’t even cook. - Richard

I was looking forward to the sourdough I’d just bought, but when I opened it at home it was still yellow and soggy inside. Clearly not baked properly. I took photos straight away to show Costco and asked for a return — fresh bread shouldn’t come out like that. - Peter

Return FAQs

What is Costco’s general return policy for most products

Most items at Costco can be returned anytime, even if opened or lightly used. Costco’s generous “no time limit” return policy prioritises member satisfaction. Electronics and major appliances, however, must be returned within 90 days. Always include all parts or accessories, and while original packaging helps, it isn’t required. Excessive misuse may void eligibility.

Does Costco offer free return shipping for online orders?

Yes, Costco provides free return shipping for online purchases. You’ll receive a prepaid label for courier or postage returns. Large items like furniture or appliances are picked up by Costco at no cost. In-store returns are always free. If a product is faulty or you return an entire order, original delivery fees are refunded too—no restocking or service charges apply.

How long does a Costco refund take after returning an item?

Refunds are usually processed immediately in-store and may take 1–3 business days to appear, depending on your bank. Online and mail returns take 7–10 days, allowing for shipping and processing time. Refunds go back to your original payment method, and you’ll get an email once it’s approved. Costco doesn’t offer partial refunds unless bonus items are missing.

Can I return something to Costco without a receipt?

Yes, Costco can usually find your purchase using your membership record. A receipt helps with cash purchases, but it’s not required for card transactions. Members have successfully returned opened or faulty items this way. Just bring the product, all accessories, and act in good faith—Costco monitors excessive returns to prevent policy misuse.

Every day you wait, your refund gets harder.
