I've had an eBay buyer win a claim against me because the shipper was not in mint condition. Everything else was as listed and mint. I've only sold a couple of times on there since then and I made sure to take pictures and note the condition of the shipper box (which is insane to me).
I've gone away from selling on eBay and starting selling here occasionally. If people ask about the shipper I'm least likely to want to deal with them because I know that it's all going to be downhill from there.
