Amex billing practices are horrible. I payed my bill in full and next month I get a bill for interest of $3.42. Amex is the only card that does this. I have never received a bill for interest from any other credit card after paying the bill in full no matter what day the bill was paid. I cancelled an Amex card 7 months ago for the same reason but for $2.01 charged in interest. Today I cancelled my last Amex card. Amex offers are not as good as they used to be and nothing good for my buisness. Amex did not look out for me as a customer. I will never use Amex again.
