Costco is expanding its partnership with Affirm to give its members in the UK a new way to pay over time with no late or hidden fees.
Whether stocking up on household essentials or investing in the latest technology, eligible Costco members shopping online can now choose Affirm at checkout and split the cost of their purchases into interest-free or interest-bearing monthly payments.
Today’s announcement builds on the successful partnership between Affirm and Costco in the US, where hundreds of thousands of Costco members have used Affirm since the partnership launched in 2025.
"Getting the best value shouldn’t stop at the price tag. It should extend to how you pay, too,” said Ruth Spratt, UK Country Manager at Affirm. “Our partnership with Costco gives UK members a simpler way to spread the cost of those big shops, with greater flexibility, no late fees, and no compounding interest.”
Affirm underwrites every transaction individually, making a real-time credit decision and only approving shoppers after an assessment of their ability to repay.
Customers always see the total cost of their purchase upfront and never pay more than they agree to.
