If you’re careful with money and are thrifty and try to shop around as well as being frugal, you can save quite a lot of money. The rewards over the long-term come as an appreciating bank account but you also have to look at how to invest your money. Since 2011 I’ve been getting good returns from Zopa and I still get over 4% which beats any bank account. My rewards for being careful are more evident now as I can afford to spend more money of a few luxuries but I still ask if I really need a product before I buy it. I bought a smart TV and other things this year and my credit card got a lot more use, but I paid it off at the end of each month.
