Chris Willman, writing at Variety:
Amazon has announced that its warehouses has “temporarily disabled shipment creation” for discretionary items through at least April 5. That doesn’t have to do with the outflow of product from Amazon, but inflow. Amazon is declaring an immediate emphasis on the kind of household and medical supplies that have been quick to sell out, and which customers are having a hard time finding in person. Their message to record labels and distributors: Please stop sending us anything, until further notice.
