About 20 new freebies at Dark Horse. They aren't added into your account unless you load them in your browser/app; various freebies disappear often and won't be in your account for free unless you previously loaded them; they aren't ordered by 'freedom' date but all jumbled in; so I don't know of any sure way of getting them all into your account except by clicking on them all. There must be a better way though; anyone know?

Anything you recommend in particular?

Most of it is stuff I haven't read yet actually, so I'm buying the first 2-3 issues of most of the series and will test them out before inevitably buying everything. But that could be a cheap way for the less impulsive among you to get a good test run before committing much cash.

The only series I've read more than tiny bits of is Justice League Dark. I love it, but the 'dark and magicy' characters in DC have always been my favorite, so I'm pretty sure that DC created this series just for me. I'm also pretty sure that I'd buy it even if it was completely blank pages.

Ugh. Another huge Dynamite bundle at www.storybundle.com

*lol* I'm looking forward to madth3s updated spreadsheet ... :)

Updated

The new StoryBundle is half-new. Unlike the Groupees bundles, is more complete in terms of arcs.

Hmmm... I'm torn between buying the impressive looking StoryBundle or waiting on the next inevitable Dynamite Humble Bundle to not spread out my collection too much. What are these Dynamite people thinking?

Agreed! Now that I have filled in some gaps caused by their bundles with other bundles, I'm kind of afraid to ever buy a Dynamite title again...

i am going to skip this one
i already have 3 dynamite bundles

I really wanted to skip this StoryBundle, but if mad's spreadsheet and my Comixology search is correct, it gives me about 50 new books for $15, so I couldn't resist. Many of those weren't definite buys at $1 sales, but at least 20 of them were, so it should be worthwhile until a future bundle makes it superfluous.

You know, screw it, I'm just going to change my paycheck to direct deposit to Dynamite and they can disperse the funds however they see fit.

From the last Dynamite StoryBundle I only bought the first tier but this time around there really seems to be enough new (and complete) stuff to warrant the full $15. Even if there inevitably will be many overlaps with future bundles from Humble Bundle or Groupees ...
