Learning to save your money is an important skill to develop. One idea is to put half of your allowance in an envelope for you to spend and the other half in another envelope for you to save. When the money in your spending envelope builds up, you can always take some out and put it with your savings.
Before buying something, give yourself a few days to think about it. You might change your mind and decide to wait to spend your money on something more worthwhile.
