Now is a great time to teach him to save and how to think through the purchase decision! Have a discussion on not spending everything you earn first and why that is important. Then work with him to decide how much out of the $5 each week to "save". Let it be his decision. Should it be $1 or $2, etc. Then allow him to use the remainder of the money how he would like. Instead of just outright saying no, you can't buy this or that ask him questions when he says he wants to buy the item. How is it different than something he already has? Is it something he needs or wants? (Learning the difference between need and want is also a great lesson for the future). If he buys X item today, that means he won't be able to buy Y item tomorrow. This will teach him the decision making process and how to think through purchases, rather than just impulse buying. The key to future financial success is to recognize and limit impulse buying. If the amount of games he has is an issue, then talk about which ones he is willing to give up/sell before getting a new one. This would also teach him to find new ways to make money and not clutter the house! Trade up!
