Buy Backspacer at Target and Get a Vault Key

This one almost slipped by me because I didn't see that this article posted by Billboard.com has multiple pages.  It appears as though shopping at Target will get you a few live shows.

The Target discs will link to a virtual "vault" of 11 concerts spanning Pearl Jam's career, from which fans can choose two. The band will also create an organic cotton T-shirt to be sold at Target, with proceeds earmarked for the hunger relief charity Feeding America. And in September, a Cameron Crowe-directed TV ad will air featuring footage shot during a private performance at Seattle's Showbox in late May.

Is that enough to make me go to Target and buy a second copy of Backspacer?  I don't know.  I guess I have a little under two months to decide.

The discussion continues here.
