Sold a $45.00 imported toy on June 11th (night), and first thing in the morning (12th), I got it ready for shipping. Due to the size, I had FedEx ground as my original option, but when I when to print the label, I noticed, Priority Mail was a close to the same price, and would get to the buyer faster. Originally, when I did the calculations, the pricing was different, making the FedEx option look cheaper. So, I switch it over to Priority Mail, and notify the buyer I was doing so, that way he/she would be able to get it sooner hopefully. I didn't get a response, but not all buyers respond to your actions, so no big deal.
Just my luck, it turns out, the Priority Mail is now over a week in transit. The last scan was yesterday still showing "in transit to next facility). I notified the buyer again (after the 5th day) to let them know I am on top of it, monitoring the package, and apologized for the delay. No response to that yet.. but once again, it's not like I'm asking a question that I expect them to reply to. The post office site mentions possible delays due to Covid, but they're talking like a day or two beyond the normal 2-3 day Priority Mail average.
The buyer has a 0 feedback (which really doesn't mean anything but thought I mention it). If by chance, they leave negative feedback due to my decision to change the shipping method, do you think eBay would remove it, despite my good intention?
