I wonder if Amazon would send this one UPS, no signature required, like they did my RF 14-35mm.
You can order three and test the hypothesis multiple times.
Correction: it was USPS. What is more interesting is my Amazon account says it was handed directly to a resident, but I found it on the doorstep and the sticker says: “Carrier: leave if no response”.
Feel free to send one my way if you need multiple data points.
