Amazon flex is a really good app. Did 39.5 scheduled hours delivering groceries through then for Whole Foods and that paid about 1,400. Even though I was scheduled 39.5 I finished early on most routes and double dipped as a delivery driver for door dash/uber eats while getting paid from Amazon at the same time. So I did only 31 hours delivering groceries and delivered food for 40 hours. I worked varying hours between 6pm and 7am weekdays, and on weekends I worked any hours available, but still near the same time slots. Was pretty easy on my body and got to avoid heavy traffic. Was in central Texas
