Yay! I've long been waiting for a new, exhaustive "Pathfinder" bundle since I only own the first three volumes (which I really liked). :-)

a new Plants vs. Zombies bundle from Dark Horse:

PDF only

Not so much a comic book bundle, but Humble is offering a 'Comic and Graphic novel audio adaptations' bundle:

Seems to be offered in MP3 format, so available offline, it seems.

A new Army of Darkness bundle on Humble:

https://www.humblebundle.com/books/army-darkness-dynamite-books

Says it's available in Pdf, Cbz & ePub formats. Many of these were offered in previous bundles, though.

From where can you buy it? I tried out several countries via VPN including of course the United States but none works (or maybe my VPN doesn't work with HB anymore - I know it did a few years ago ...).

we need someone from US to try to gift this bundle. I'd be interested (I can buy&gift a GOG game or send money via paypal - of course there will be some extra $ for taking care of it).

Oddly, I was able to buy it from Mexico. No VPN needed.
Not the usual regional lock, it seems.

When the cousin of a friend of an acquaintance tried buying from HB with a VPN, they had to do it without an account because the account had been tied to a specific country.

A new Top Shelf and IDW bundle on Fanatical, alas, not as luring as the Humble bundle one:

Seems to be PDF only. Many of these have been bundled in the past.

I’lll help you out if you’d like.

Yeah, I already thought that could be the problem - but my comics backlog is more than big enough so I won't bother to try to buy a regionally locked bundle (and it probably has some repeats anyway) ...

Are you certain this would work? (Or if not, are you willing to take a ~$20 risk?)
If so, then:
CrossCode with all of its DLCs currently costs $19.64 on discount. Is that close enough to the $18 price of the Top Shelf bundle for you?
I'm in the USA (where, yes, it's purchasable), and I'd be happy to try to make that exchange.
(Though I suspect Bynch would be a better option for you.)

Also, would you like to adjust the payout spread between IDW, BINC, & Humble, or just go with default?

I'm not certain, but I'll take that risk.It should work, but I also have another solution in mind.

CrossCode will be ok, and default split is ok for me, but you can adjust it as you prefer.

Please confirm that your offer is still valid and I'll buy CrossCode + DLCs as a gift.

@Bynch
I really appreciate the offer, thanks. I'll go with Curtainferno because the details are already speciied. If Curtainferno is no longer intrested, I'll take your offer.
