These Grandparents Make $10,000 a Month on Their Delivery Side Hustle, With Free Workcations — 'We Hit a Hotel With a Pool' These seniors started driving for Instacart and Doordash, then added apps from there. Within a few months, the "Gigging Grandparents" had turned a part-time delivery gig into a comfortable living.

In their late 50s, Day and Al Stefanelli found themselves in a tough financial spot. They needed to make some money — and fast. So they looked around at what they could use and saw one unairconditioned Jeep. It was not ideal in Atlanta, but it was something.

So the Stefanellis downloaded the basic driver delivery apps, and hopped behind the wheel. Fast forward to today, and the couple has gone from making a couple hundred bucks here or there on deliveries, to $10,000 a month. Fortunately, for anyone else interested in driving their way to a six-figure annual income, the Stefanellis are sharing their strategies.
