™ strongly recommends using Debit Cards (in credit) or PayPal (in credit), instead of withdrawing from your Credit Card (in debit). Why? Debt, with interest, gets families into trouble. And as you would learn from the “Financial Maths” section of the product, a monthly interest rate of 1.53% approximates to an annual rate of 20%. Even though credit-card companies must by law advertise their interest rates as yearly APR rates, it’s still a rip-off. Otherwise maybe you’ll pay 20% extra for what you purchase, and more, especially if you don’t manage to make your repayments on time and perhaps incur extra charges – or worse.


We should also remember that interest, or “usury” as it was called before, has only recently been regarded as socially acceptable in the last few decades. Before that, it was frowned upon. In the religious texts, it is spoken against, for example Psalms:15:5, Exodus:22:25, Koran:2:275.

So if you must use a credit card, please, keep it in credit, and make your purchase from your available positive balance. You’ll need to first check with your bank, but, normally you’ll not be charged interest on payments made where the account is in credit. And watch out for those yearly governmental charges and service fees from your bank in case it tips your balance “into the red”.
