So having sold a large item (plastic wall cladding sheets, about 1kg, but 1 metre long) I had the joy of "simple" delivery to content with. Only option for the size was the large size, which it turns out is DHL collecting it. No option to drop off, has to be collected, and must be someone at home to sign(?), and the pick up window is 6am to 6pm. Hardly worth bothering for a £10 item (£12 delivery), but decided to stay home and wait. And wait. And wait. Eventually eBay updates with "not collected, premises closed" which is funny for a family home, with me working in the garage in plain sight of the entrance gates and 2-3 other members of the family around. After 45 minutes going in circles with the eBay AI, I learn they will try 3 "more" times. Bottom line: DO NOT BOTHER SELLING ANYTHING OVERSIZE. You will be completely dependent on DHL and their pants are on fire.
