While a credit card can be a great way to manage your money if used wisely, there are certain things you should never buy with credit. This includes foreign currency or anything to do with gambling, such as betting chips or deposits for online casinos. This is because you’re using the credit card to buy money, and you’ll be charged additional fees accordingly.
In a similar vein, never use a credit card to withdraw cash from an ATM – again, you’ll be charged additional fees, and you’ll also be charged interest from the moment it’s withdrawn, rather than from the following month (as per other purchases).
