Many people view credit cards as a bad thing – something that encourages us to get into debt, making the credit card companies a lot of cash from the interest we pay. However, the best way to use a credit card is to use it to your own advantage and actually make money from it. This is known as stoozing.
First of all pick a credit card which gives you a long introductory 0% rate on new purchases, then simply make all your purchases on this card for the length of your 0% rate. Every time you make a purchase, you should put the equivalent amount of money into a high interest savings account, so that it is still being withdrawn from your regular current account. Set up a direct debit to pay the minimum payment on your credit card each month.
At the end of your introductory rate, simply withdraw the balance of your credit card from your savings account to pay it off before you are charged any interest. The key point to note here is that since you have been earning a high interest rate on this balance in your savings account, you now have this pot of interest left which you have made just from cleverly using your credit card.
