X-link to the DRM-free thread for some new bundles:
Humble Book Bundle Neil Gaiman contains a lot of repeats from the Neil Gaiman Rarities bundle, but also has some new stuff in it, and it's good value if you missed the last one.
Valiant Universe from Bundle of Holding features both the tie-in RPG gamebooks, and Vol. 1 in many series of the comic books the RPG was based upon. Again, there's a bunch of overlap with the Valiant HB from ages ago, but there also looks to be some new stuff in it.
