This very problem is why I have been avoiding online purchases. I am fortunate enough to live in an area where most items and services are readily available. On Saturday mornings my wife and I go out for breakfast together, then run errands and go do our shopping. Since I spend so much time away from home for work, we look forward to our Saturday mornings together each week.
My sister is a postal carrier, and she says that the postal service is suffering from the same labor shortages as every other industry, and Covid infections just make it worse especially if they end up with more than one person gone at the same time for their 14-day quarantine. She also says that delivery issues within the postal service seem to affect some areas more severely than others.
At the same time that the transportation industry is having people shortages, Door Dash seems to be doing well. We were out to a local Mexican restaurant for supper last night and the Door Dash drivers showed up five times in one hour to pick up meals for delivery. I was quite surprised.
