Existing members know the value of a Costco membership, so what do you do if a friend wants to join? Refer a Friend!
Refer a friend before 31/08/25 and both of you will receive a £10 Costco shopping voucher and a complimentary Kirkland Signature Hot Dog & Soda, which can be redeemed at any of our 29 UK warehouses. The voucher is not eligible to be redeemed online.
Visit the warehouse and head to the membership desk to introduce a friend to the benefits of a Costco membership.
Here's how the process will work:
- Visit the membership desk. Both you and your friend must be present to qualify for the Refer a Friend promotion. Make sure that you have your Costco membership card and that your friend has valid ID* to sign up. Membership criteria applies.
- Mention to the membership employee that you are there for the Refer a Friend promotion.
- Each of you wil receive a £10 Costco shopping voucher and a free Kirkland Signature Hot Dog & Soda in person after your friend's new membership is activated. Once activated, your Costco membership is valid at all 29 UK warehouse locations plus over 862 locations worldwide.
