Over on Comixology, last years Infestation crossover is on sale for 99 cents each until Thursday, January 26, 2012.
Infestation: G.I. Joe 1-2
Infestation: Ghostbusters 1-2
Infestation: Star Trek 1-2

I only read the first few issues of this when it came out, but I enjoyed it for the most part. I just wasn’t going to keep driving 45 minutes every week to find a comic shop to pick them up.
