I sold something on Marketplace about a week ago and had Corona show up in my driveway. Yeah, the guy was wearing a pair of shorts with the Corona beer logo on them.
We were wearing work gloves, but neither of us had masks on. The cash I handled with my gloves on and later I sprayed it with Lysol.
Before corona, I've had a few people pay me via PayPal even though they were picking up the item. That might be an option even more so now.
