Soaring demand for online food delivery during the coronavirus pandemic has forced Amazon to create a waitlist for new shoppers. It’s part of a number of changes Amazon is making to its food delivery business.

Shoppers who want to order through Whole Food or Amazon Fresh have recently found it nearly impossible to find an open delivery or pickup slot. Beginning Monday, Amazon said it’s requiring new customers that want to use those services to “sign up for an invitation” to help it handle the demand crush.
