The eBay auction includes a set visit for the day (plus you're allowed to bring a friend), a meet and greet with the cast for one whole hour (which is actually a really long time to have to hang out with Kirsten Dunst), a walk-on/extra role, a trip to the premiere, and outfits for said premiere (apparently you can't wear spidey PJs). I'm all for using scifi for a good cause, so if you've got the cash, go for it. Bidding ends Sept. 5.
