Everyone seems to agree the method of shipping was completely unreasonable. Most, but not all, think the seller is responsible for the damage that occurred after the item arrived. The question I raised earlier is assuming the seller tells ebay the item arrived undamaged but that it was damaged in opening the package because the method of packing was unreasonable, what is ebay likely to do in that situation ? I guess we will find out.
I have personally come closer to damaging cards I received because they were entombed in tape and bubble wrap to protect them

Patience in opening is a true virtue.
I have to say Frank, I have not yet experienced the block of ice shipping method
