I didn’t realize you hadn’t bought one yet. The used market is indeed pretty slim on FM. Hope you find one.
This makes me curious if some others are as ridiculously overcautious as me: I’ve got a lens or two that I definitely plan to sell, but have been absolutely unwilling to take any unnecessary trips to the Post Office until this nightmare time is over. For example, I’m especially eager to post my 12-24G on FM so I can replace it with a Sigma 14-24, but that’s all postponed until after the vaccine is coursing through my veins.
I don't know about Georgia, but the Post Offices here are as safe as our grocery stores. I use Click-N-Ship, print the label at home, and my local USPS has a separate window for Click-N-Ship drop offs.
IIRC, some areas also have a PickUp option.
