Humble Bundle has rolled out the second Transformers bundle, with up to $155 worth of IDW Publishing's comics starring the robots in disguise.

There's a bit of a catch, however: The offer runs for just one week, ending Wednesday, March 11, at 11 a.m. PT.

As you probably know by now, Humble Bundle allows you to name your price for DRM-free downloads in multiple formats, including CBZ, PDF and ePub, with a portion of proceeds going to charity. In this case, it's the Hasbro Children's Fund.

This offer allows you to pay what you want (as little as 1 cent) for the first 37 issues of Transformers: More Than Meets the Eye. If you pay more than the average price offered for the bundle (at the moment, that's $7.37), you'll also get volumes 1-6 of Transformers: Robots in Disguise and the first volume of Transformers: Dark Cybertron.

If you pay at least $5 above the average price, you'll also unlock Transformers: Days of Deception #35-37, Transformers: Robots in Disguise #33-34 and Transformers: Dark Cybertron Vol. 2.
