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 31/12/2024 and both of you wil receive a £10 Costco shopping voucher and a complimentary slice of Four Cheese or Pepperoni Pizza, 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:

  1. 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.
  2. Mention to the membership employee that you are there for the Refer a Friend promotion.
  3. Each of you wil receive a £10 Costco shopping voucher and free slice of pizza in person after your friend's new membership is activated. Once activated, your Costco membership card is valid at all 29 UK warehouse locations plus over 862 locations worldwide.
