I too am very unhappy with Simple Delivery. A) it's not simple, and b) it has taken away my ability to choose the best and cheapest postage price. Simple delivery for me is weighing my items at home and going to a post office and knowing exactly what it will cost me, no messing. I tried to contact customer service but it was a series of dumb AI conversations. Seriously thinking of stopping selling on ebay. I've done it for 20+ years, (just offloading my books etc when I've read them), and this is the worst it's ever been.
