Buyer can file a claim through ebay, paypal, and if the item was insured through the postal service. Once the buyer agreed to ship, he/she became liable to do it properly even if here is a written agreement releasing the buyer. It can be argued that the seller committed gross negligence by not using any padding. Ebay tends to be very buyer oriented, so the buyer should win.

You can do an ebay or a paypal dispute if you used that service. If you used your credit card you can also dispute there too. You might find the Paypal process best in conjunction with a credit card dispute, if applicable. Ebay can be a bit strange and inconsistent in its outcomes when the fact pattern deviates from the norm.
