If you didn't buy your currency from Asda or didn't opt for a specific guarantee, you can still sell your leftover banknotes at any Asda Travel Money bureau.

You must keep your original receipt or confirmation email to prove the rate you paid. 3. Comparing Buy-Back Rates

Asda does not charge commission on currency buy-backs, even if you originally purchased the money from a different provider like the Post Office or Tesco.

For those who want to "inflation-proof" their holiday cash, the Asda Buy Back Promise is an optional add-on that protects your original exchange rate.

For a flat fee of £2.99 , Asda guarantees to buy back your leftover banknotes at the exact same exchange rate you originally paid.
