+1 for that good sir!
I really love the fact Image Comics went full DRM-free!

Does Comixology have seasonal sales, something like Steam or GOG summer/winter sale (where most of the games in the catalog are discounted)?

To the best of my recollection, no

ok. Thanks.

A new cosmic sale today only (8/4/14) for Marvel on Thanos.

https://www.comixology.com/Thanos-Sale!/page/2925?tid=B140803001_Marvel_Marvel_Monday_Thanos

All 18 issues of the Infinity Trilogy, all 12 issues of the Thanos 2002-3 series, and 40 misc. issues over the years with cosmic. Appearances.

I have always avoided cosmic marvel, meaning to get into it 'some rainy day'; but I'll need 40 of them to finish all this new reading from these constant cosmic sales.

Berserker Volume 1 from Top Cow is available as a watermarked PDF for $4.99 at DriveThruComics. It collects issues #0-6

From IDW, a Teenage Mutant Ninja Turtles sale until 8/11/14.

And the usually weekly Tuesday DC sale appears to be Vertigo's DMZ, just the collections.

I'm on vacation the next several days, so don't be surprised if I miss some things or even don't post at all.

I'll try to keep an eye on comixology and Dark Horse (I have them on twitter, so it should not be too hard)
Enjoy your vacation!

Edit: Comics added to the BTA level.

1. Yes, presently they don't offer their comics DRM Free anywhere else. They might do so in the future through comixology, following the steps of Image, Dynamite and the rest, but they might not. (IDW put Dr Who in a bundle and they have not gone DRM Free in comixology)

2. I updated the announcement to reflect that six of the offered series are complete series that amount to 30 issues (22 for the BTA tier). The chance to get those comics in digital form for $15 outside of this bundle is very slim, so even discounting partial series it's a god digital deal.

Opinion: Personally, I plan to buy it. I have not done so yet as I don't want to put more in the credit card at the moment. :)

I'm surprised a lot of these Boom comics seem to be current releases. Sons of Anarchy includes up to the July 2014 issue so while not complete it's up to day with all releases so far. Same for Evil Empire, Robocop, Lumberjanes, Dead Letters, and probably some others. That makes me curious to see if next week we will get unlocks of the August issues.

Although it's not indicated as a "complete series" the Planet of the Apes volumes are a complete collection as only 16 issues were releases in that line (there may be an upcoming special to tie up loose ends). Boom ended that series and published a few different series in the Plant of the Apes universe, not sure if those build on one another.

I wish they'd release the first two volumes of Mouse Guard as it has been generally praised and I have not read it. Although I don't follow reviews much, I've seen good things about Hacktivist and Lumberjanes.

Good to know. Thank you!
