6. Buy Gift Cards
A good way to encourage your family members to stick to their assigned budgets is to put the amount they are allowed to spend onto a gift card. Not only will this help them stick to their limit, it can also save you a bit of money if you choose to purchase discounted Disney gift cards. This can be done by using a Target Redcard to buy them from Target or purchasing discounted cards from Raise.com (or a similar website).
