A service that lets you try high end items before you buy. So example speakers or TV or drones, you get to try them for a week and then decide if you want to keep it. If you do you're charged the price of the item, if not you can return it for free. My idea was to charge brands for the service and handle fulfillment and we keep a % of sales made.
A couple of years ago I had a similar idea as you.
