not much i can do with a damaged comic, but we'll see what happens.
last time i tried to offer optional insurance in an auction, ebay said i couldn't do that. i had to either include it in the price or leave it out, so i leave it out and leave it up to the buyer to ask for insurance if they want it. as a buyer i will ask about insurance if i think the item and price demands it.
are you sure you didn't miss something.
Its been six months since I sold but I always include an option extra insurance amount in the shipping section when doing auctions. They have a box there specifically for insurance...at least they did?
