If you normally charge all of your purchases on your credit card, and then you don’t pay off your credit cards in full every month, because of added interest charges you are probably paying at least 50% more for everything you buy. If you are relying on your credit cards to afford your lifestyle, break your expensive credit habit by saving up for your purchases ahead of time.
With savings, you can buy things when they are on sale and take the time to make better spending choices. People with savings can also stockpile groceries when they are on sale (items that are non perishable or which can be frozen). One author suggests people who do this can possibly skip one grocery shop a month and save 24% a year on their grocery bill.
