Hey, DavieDude!
I just bought a DVD from my local Wal-Mart and they had two kinds for sale - the bonus one and the regular one. I don't know what is inside the bonus pack, but I bought the regular DVD. It had a sticker on the outside that indicated that a VMK code was enclosed. So unless you are buying the film because you love Herbie (I have no intention of ever watching the film!) I would buy the one that is clearly marked VMK.
