Kevin O'Leary has an estimated fortune of about $400M (£295M), three homes, and a regular seat on the Shark Tank panel. Recently, he spent part of a shopping trip standing in a Walmart aisle, weighing up paper towel packs to get the better deal.
The Canadian investor, 72, filmed the run for Instagram after his wife handed him a shopping list of everyday essentials: batteries, butter, paper towels, and OxiClean laundry spray. The video then ran through the bargains he returns to.
