>>>>I think all buyers should understand the shipping and insurance terms and conditions prior to bidding. If the buyer is paying for shipping and the buyer wants insurance, they buyer should make sure they are paying for it. It is too late get insurance after the package is lost.

Except in the case where the Seller specifically disclaims liability in the auction description (which you say you do), it is not the Buyer's obligation to get insurance. It is the Sellers obligation to deliver the goods and the Seller takes the risk of shipping.
