Don't worry, I know how to use the credit cards to my advantage
Just pick up a no-interest-for-12-months deal, and drop the card after 12 months. Of course, you can't use the card for purchases or else the company will decide that you have to pay your original debt first and the purchases will quickly accumulate interest. It's really quite easy to abuse the credit card companies, and I don't feel guilty about it either considering their conduct.
