I got mine at a Target too with no VMK label but did the shaking thing first We had been wanting that movie anyways so it was a win win situation!!!! At least that's what I keep telling myself!
There is defintely a different sound to the Herbie box. I compared it to other Disney DVD's and Herbie was the only on that sounded like it had something loose in it. Good luck! Cawa is very glad to be out of the bargain bin!
