It never ceases to amaze me how ignorant people are about proper packing. I received a glass item once (not eBay) which the shipper merely slipped into a bubble lined envelope. Of course it was broken when it arrived.
I sort of wondered if the piece wasn't already broken when it was mailed. Thje seller was so defensive and even down right offensive. It was wrapped once in thin bubble wrap and in a very narrow box. There wasn't anything to cushion it.
Kindest person I have dealt with was an elderly gentleman who I purchased a GwtW lamp from, when he was geting it ready to ship, he knocked it off the table and it broke. He was so sorry and sent repeated aplogies. He also refunded my money right away.
