Why change the way we do things all the time? A buyer buys an item, pays and you pack it, take to the post office line up and pay the postage for whatever service you the seller choose for security reasons.
I only use Royal Mail, certainly not EVRi as they just place your stuff on the doorstep take a photo sometimes and leave it there, YODEL is too far to drop off(5 miles) .A lot of the drop off at convenience stores just have a bag at the end of the shop no always within the sight of the shop staff so anyone could steal items.
Now it's all QR codes and print your self labels.
Why not leave it simple?
