Yes. one courier broke a heavy speaker that I sent in for repair  but the shop had prepaid the courier (DPD) and they thought it was insufficiently packaged & so my item (originally  bought on ebay) came back with chunks out of the casing they must have dropped it. Luckily it still works. I used to sell larger electrical things on ebay but gave up because the couriers incl. parcelforce broke some items althou their insurance always paid. Now I only sell such things on collection only or facebook and will only send lighter things via courier
