Costco Frequently Asked Questions

Costco Loyalty Programme

Costco offers a rewarding loyalty option through its Executive Membership. By upgrading, you’ll earn a 2% annual reward on most Costco purchases, up to £750 per year. This reward can be redeemed at any Costco warehouse and is a brilliant way to save if you're a regular shopper. Executive Members also get access to additional perks and exclusive offers, making the small upgrade fee well worth the investment. Whether you’re buying in bulk or just stocking up on essentials, the more you spend, the more you save.

Costco Refer A Friend Discount

Costco’s Refer a Friend scheme is worth looking into. When your friend activates their membership, you both get a £10 Costco shopping voucher and a free Kirkland Signature Hot Dog & Soda in person. It’s a win-win for both you and the person you're referring.

Costco NHS Discount

There’s good news for healthcare workers! The Costco NHS discount gives NHS workers a £10 online voucher. This offer can be used alongside other Costco voucher codes for even bigger savings on your next bulk buy.

Costco Free Delivery

Costco includes delivery charges in most online product prices, so you won’t be hit with unexpected fees. Free delivery may not apply to Business Delivery Items, so always check the product page. Look out for occasional Costco free delivery voucher codes in our Voucherbox listings for extra savings.

Costco Student Discount

Currently, there’s no Costco student discount available. That said, students can still save big thanks to everyday low prices and our regularly updated Costco voucher codes, which can help stretch your budget a little further with each shop.

Costco First Order Discount

Costco does not offer a specific discount for first-time orders. However, new members can still find value with a Costco voucher code or one of the latest Costco deals listed on our site. It’s always worth checking before you checkout.

Costco Newsletter Discount

At the moment, there is no Costco newsletter discount available for subscribers. That said, signing up still gives you the latest Costco offers, promotions and online deals straight to your inbox.

Costco App Discount

The Costco app is a must-have for savvy shoppers. While there’s no official discount, the app gives you access to exclusive promotions and in-app Costco deals that can’t be found anywhere else. Just search “Costco app” from Google or Apple Store to download.

Costco Over-60s Discount

Costco doesn’t currently offer a dedicated discount for over-60s. However, Gold Star Membership is available to anyone aged 16 and over, including retired professionals from certain industries, making it broadly accessible.

Costco Teacher Discount

At this time, there’s no Costco teacher discount available. Teachers can still benefit from warehouse prices and check our latest Costco voucher codes for seasonal savings and special offers.

How to register for a membership card

To shop at Costco, you’ll need to register for a membership. You can do this online or in person at your nearest warehouse. Choose between Gold Star or Business Membership depending on your needs. Once your membership is approved, you’ll receive your Costco membership card, giving you access to all 29 UK locations and over 860 stores worldwide.

Executive Membership

Costco’s Executive Membership offers excellent value. For Executive Business members, the fee is £65 plus VAT, while Executive Gold Star members pay £70 plus VAT annually. Both options come with a free card for a spouse or domestic partner. If you're already a member, you can upgrade to Executive at a pro-rata rate based on how many months remain on your current plan. This upgrade unlocks additional perks including annual 2% cashback.

What to do if your Costco discount code isn’t working

If your Costco voucher code isn’t applying correctly, don’t worry, it happens! First, double-check the expiry date to make sure the code is still valid. Then, review the terms and conditions to confirm that your items meet any specific requirements such as minimum spend or eligible categories. Also, ensure you’ve entered the code exactly as shown. Watch out for typos or extra spaces. Still not working? Try a different Costco discount code from our page. Some codes may only be valid for certain users or locations, so testing a few different ones can help you find the best fit.
