CIBC Mastercard 客户常见问题解答

Yes, you can use your CIBC Mastercard at Costco stores in the U.S. You just need to swipe or insert your card at the card terminal when it's time to pay. However, please be aware of any foreign transaction fees that may apply. Also, remember to inform CIBC about your travel plans to avoid any unnecessary blocks on your card due to unusual activity. It's also always a good idea to have a backup payment option in case you encounter any issues.
