Ask your parents if they'll pay you for doing more chores. You're probably already expected to do chores around the house and help out your family for free. If you need a little extra pocket change, however, ask your parents if there's something else you can do for a small fee. For instance, maybe your mom really hates folding laundry and would be willing to pay $5 a week for you to do it instead. Whatever it is, let your parents know you're willing to take on more work for a bit of allowance.
Using a food delivery service can’t necessarily earn you money, but it can help you save you money if you constantly find yourself throwing out half the food you buy. Food delivery services send a box of food every week with new, sometimes unique vegetables, meat, fruit, and so on. If you don’t have time to shop and want simple meal-prep that leads to a good meal, a food subscription service may be perfect for you.
