It is the Seller's/Shipper's problem. Don't open the package and take pictures of the damage. Contact the Seller and ask them what they are going to do. They need to take it up with USPS. The shipper is responsible for proper packaging and safe shipping to you and buying Insurance if necessary.
If the Seller does not make it right then you definitely contest the charge with your Credit Card. The Credit Card company won't "eat the charges" as one poster stated. They will just take the money back from the Seller.
