Savin\' Up for Pearl Jam

No, not the concert. I already have some kick-ass tix for the October 28 show at Glen Helen. I'm talking about saving up for the 25, yes 25 double-CD sets that are going to be released on September 26. These are "official" bootlegs from PJ's European tour this year, each set corresponding to a concert show. Amazon.com already has these ready for preorder at about 12 bucks a pop. Doing the math, that's $300 right there for all 25 CDs, not including tax and shipping. I already know I want them all. The question is, should I get them all at once or over time? It all depends on whether or not these are a limited release. I would imagine so, since it would be impractical for stores to make the space for all these CDs...
