Yep-- high risk during covid and lack of local delivery capacity, not to mention empty store shelves, meant Amazon Fresh was the alternative. I was fortunate that literally just a few weeks before the shutdown I had been sick and couldn't go foodshopping so I used Fresh for the first time. That made me an existing customer, and when the shutdown hit they weren't taking new ones.
Even then, I was up to 1:00am in the morning a lot of times waiting for delivery slots to open. And then Amazon began releasing delivery slots incrementally throughout the day, which probably made it more equitable but also meant I had to constantly refresh the checkout page a dozen times an hour to get one instead of being quick on the draw after midnight.
