The Official Ozzy Osbourne Site | The official Ozzy Osbourne site

Newbie here ... cannot wait for Ozzy at the Oakland Arena! I always hate it when you go to any concert and souvenirs are more expensive at the venue than online. Is this the case here? If so, how much more pricey are the items? I am totally into that Ozzy "crucified" tee shirt and logo hoodie with "Black Rain" on the lower back. Are there any "exclusive" items at the shows, or is it all the same stuff sold through
