Boomerang gift

A gift whose value or benefit accrues as much or more to the giver as the recipient. Examples: You give your partner season tickets knowing full well that you will always go together. Or you give a woman beautiful lingerie that you will appreciate as much as she. Or you take a date to dinner at a restaurant you both enjoy.

"The next present was obviously a boomerang gift, but that's all right. I wanted it anyway."
