I happened to do a quick search for the first pitch inserts because they caught my eye in the pre-release info. I particularly want these two:
Eddie Vedder and Jack White. Two of my favorites from the music biz. What I found was that apparently there is quite the demand for these two right now. One Jack white auction was at $21 plus shipping with 4 hours left, a whopping 26 bids so far(as I'm writing this draft)! A few Eddie presales topped $18 and most of the auctions ending in the next few hours were hovering around $10-15. Fortunately enough, I have a decent chance of getting at least one of the EV cards since I've got the Cubbies in a jumbo case break that should be happening pretty soon. Hopefully finding a Jack White for the collection won't end up breaking the bank.
