Cash back, reward cards and air miles

Some credit cards pay 5% cash back back every time you make a purchase and give you the savings quarterly or yearly, that is money that could be kept in your pocket!                       Some Reward cards work much the same way, they give back when you spend.  Invest the savings into some passive income and earn more then a return!  

Travel mile cards will pay you mils every time you make a purchase, some travel mile cards have an added bonus for signing up, 5,7 and even 8 thousand air miles are added when you sign up, the con here is that you need to spend different amounts  depending on the card to get the bonus miles but with a large enough family that shouldn't be a problem.
