Whether you purchase from a store or private seller, the seller should take full responsibilty for packing the item in a manner that will provide substantial protection. Do stores charge for the proper packing? Not to my knowledge. Should sellers charge for packing the item, even if it requires double boxing? As a seller, I wouldn't charge for it; and as a buyer, I wouldn't pay for it. As a seller, I would want the buyer to receive the item in the condition it was advertised as. To assure the packing is adequate, I always over pack, and over tape.
