I wouldn't accept it...I would call the dealer and let them know AS SOON AS HUMANLY POSSIBLE!!! The more time you wait will seem like you neglected the instrument, and may result in either a longer wait to be satisfied, inferior results, or no satisfaction at all!
Would you have bought the instrument in this condition new off the wall at a store? If yes than enjoy your instrument, if not, run to the phone and get the right instrument for what you paid!!!
As far as resale, I wouldn't buy your guitar and pay what you paid a week later without the crack in it. So with the crack will definitely bring the price down...
By the way there weren't any pics.
