Game Over, Dad

Ethan Stone is a technology vice president at an internet company on half a million a year, and he hands his salary to his wife and daughter. He spends 368 on a game he played when he was young. His daughter finds the purchase and starts a campaign against him online, and the harassment lands him in hospital with a heart attack. In the hospital bed he decides to spend on himself for once. A refund system attaches itself to him: anything he buys for his own use comes back at a hundred times what he paid. He then learns that his wife, his daughter and his brother-in-law are arranging to take the house his dead parents left him, and he sets about making them pay for it.
