Suppose you consigned these, instead. You ship them and CIS covers the books or the art in shipping. They arrive and two days later the persons dogs rip them to shreds. Are they covered?
By the way, your collectors policy covers your books, but if you sell extensively on ebay, they may not fully cover your shipping. The person I spoke to told me there is no exact number that changes a collector into a dealer, but if you are a power seller selling mostly comics, you need a dealers policy . Not a collectors.
I'm not 100% thrilled with CIS. They are giving me problems on a few items from my flood, but overall they have been pretty damn good.
