When you buy (birthday, christmas) gifts for your kids 18 and under, living in your home. Such as, Electronics, clothes, toys, blankets, etc. Would you allow them to sell these items and keep the money, if they no longer wanted it? Even if their are other kids in the house who could use it.
Forgot to add example:
Dd has gotten dresses over the years, wants to sell them. I want her little sis wear them.
Another child has video games that other kids in the house have been playing for years, now wants to sell them.
