Mance, one week before his eighteenth birthday, purchased a DVD player from the Computer Outlet store and paid $150 cash for the item. A week after his birthday, he purchased a handheld police scanner for $95 from Radio Shack and also paid cash. A week after he purchased the police scanner, Mance wished to disaffirm both contracts and recover $150 from the Computer Outlet store and $95 from Radio Shack. Will Mance be allowed to disaffirm one, both, or neither of these contracts, assuming that both purchases were within the guidelines of selling to minors?
