Some people play balance transfer game. They get 0% APR credit card from a Bank-A and do the balance transfer of their existing debt to the new credit card. They pay the full amount to the credit card before 0% Intro rate expires. When the intro rate about to expire, they get the new credit card with 0% APR from Bank-B and balance transfer the debt from Bank-A to Bank-B. The cycle continues until they don’t get 0% offer anymore.

This is a nice way of keeping the debt at 0%, so no interest needs to be paid. Only catch is that if they miss the monthly payment for the credit card, the banks will hike the interest rate to 13% from 0%. If the customer forgets to pay the full amount before the 0% offer expires, he/she will have to pay interest on the balance remaining after the 0% offer expires. If you are interested in this pursuing this strategy, it’s better to keep a spreadsheet detailing the cards you received with 0% APR. The spreadsheet should have the information about card, issuing bank, issued date, start date of 0% offer and expiration of 0% offer. Also, use your outlook program or other reminder software such as Memo To Me to remind you about upcoming 0% offer expiration.
