Big Humble Comics Bundle "Dynamic Forces 25th Anniversary":
https://www.humblebundle.com/books/dynamic-25th-books?hmb_source=navbar&hmb_medium=product_tile&hmb_campaign=tile_index_5

Edit: The following is my original text with some unfortunately wrong assumptions about some items. The correction is in post 1523 of this thread.


That could very well be the best Dynamite bundle yet with very few bundle repeats (I think "Prophecy" is the only one that was featured in earlier bundles in complete) and if my research is correct - I haven't bought the bundle yet so I cannot check it - there should be some really big collections in it that one can easily overlook. For example, "The Shadow Master Series #1-3" should be Vol. 1-3 which is a complete 19 issue series. And "Vampirella: The Essential Warren Years" is a 37 issue compendium of the 1970s series!
But as I said: As long as no one bought the bundle and checks it (I will probably wait for a better exchange rate) that's an information without guarantee ...

I will definitely buy the $15 tier, maybe even the $25 tier.

Also: "Dept. H Megabundle" from Dark Horse for $9,99 containing the whole series BUT the (just released) final issue #24:

And a "Resident Alien Megabundle" for $4,99:

There is a blind pre-order for a Markosia Comics Bundle on Groupees:

https://groupees.com/markosia

I have no idea about their comics but it says the bundle will have 24 files, maybe single issues and/or volumes.

I'd like to hear more opinions on this one.

Thankfully I own none of those (or of the rest) so I'm glad I preordered. Of course I don't know about the quality but for a Groupees comics bundle it contains surprisingly many comics and all of them are complete stories!

Okay, now I bought the current Humble Bundle and unfortunately I was mostly wrong concerning my aforementioned examples: "The Shadow Master Series #1-3" is indeed just three out of 19 issues (Vol. 1 has the same cover as #1 and since the complete series is featured in three volumes I wrongly concluded it would be the whole series) and not even a complete story arc (but that was included in an earlier Comixology bundle I own so that's no loss for me ...).

And "Vampirella: The Essential Warren Years" does NOT include 37 issues of "Vampirella Magazine", but "material from issues 1, 2, 8, 9 and 11-37". But at least it's still 450 pages so that's really not bad.

I certainly don't regret buying the bundle but obviously it could have been an even better bundle.

I'm not particularly fond of Dynamite comics but a DRM-free copy of that Art of Atari book is tempting me... If you purchased the bundle at the $25 tier, Geddes17, would you mind checking it for quality? Would you say it's printworthy?

While I'm at it, I spotted a couple of free Marvel comics:

Guardians Team-Up (2015) #1
Gwenpool, The Unbelievable (2016-) #1

On Marvel freebies, they haven’t been doing the usual 4 new freebies every month or so for quite awhile now. But checking the Marvel iOS app the other day, I found dozens of new-to-me freebies.

Sorry, I went with the $15 tier. But if you don't want to buy the whole bundle, amazon.com has the book for $16,82. Ah, I see, you're from Portugal so there are additional shipping costs of course - but at least you've got an alternative to the Humble Bundle ...

Edit: And it's at €20,04 from amazon.es which will probably have much lesser shipping costs to Portugal ...

The bundle has reached both bonus goals so four additional comics have been added to the base tier ($2). It runs for three more days.

Amazon is having a Marvel digital graphic novel sale for 99 cents each. Every URL that I can find is a mess and I doubt the forums will take it. This is the best I can do:

There is a pre-order for an Indie Comics Bundle on Groupees:

https://groupees.com/fistfulofindiecomics

Apparently it has "adult content" because it asked me to verify my birth date before payment.

11 comics minimum with bonus content
