New Submit sale is 50% off the series She Died in Terreboone, with code NOIR. The four single issues total more pages than the collection for the completest. The first issue was previously free iirc; it was a good enough read to get me to buy the rest. Code expires 5/20/15.

The weekend Dark Horse sale should be up soon. I'm not sure if it'll be that Project Black Sky sale that leaked early, or if that was just an old code that still works.
https://digital.darkhorse.com

The PBSDHD50 code overlaps with the weekend sale for X v2 1-10 making them $0.50 each.

I grabbed a bunch of the freebies, but got a download error when going to the download page.

Luckily they were freebies, so I'm not out any money, but I think I figured the problem. My Fire Phone won't open them, which is strange, as I can read books and magazines on my phone.

What app/site/company?

This $10 book free at Comixology with code makingstarwars.

Hmm, my Kindle Fire runs the Comixology app just fine, but I don't know much about the Fire phone.

You might check your in app Comixology settings to ensure the download location is good (versus trying to write on flaky external storage). I'm able to open Comixologg issues on my LG G3 and iPod Touch so phone should work. Amazon owns both Kindle and Comxiology so I'd expect compatibility. Comixology has good support via email or Twitter so if you cant figure it out I'd ask them directly.

Two new sales at Comixology this Memorial Day, neither themed to this day of honoring those who gave their all for our freedoms.

From Hexagon, the 1960s Tarzan-like series Zembla is on sale, five volumes at $.98 each, unknown duration. Has anyone ever read this?

Humble Bundle just put up a new listing for IDW/Top Shelf books. Notably this lot includes Locke & Key vol 1-6, League of Extraordinary Gentlemen vol 3 with more on the way...

I think I have most of these on Comixology, but that 'more on the way' is usually good enough to be worth an automatic purchase.

Locke and Key, LXG and Parker make this the most automatic buy of any recent deal I've seen. I can't wait to see what else is added. Hopefully they throw in the other Parker books.

At this point the latest LOEG and March Book 2 are the only things that appeal to me in there that I don't already have. If they add some stuff, I may take another look.

But if you don't have any of this stuff, it's a great deal.

You all should already be buying this neat little indy, but The Dead #1 is free with code DEADPOD.

And in a different transaction you can use code HOCKEY to get any of the 7 issues and 2 collections of the series Hockeyapocalypse for 50% off.

Do they ever have a line wide DC or Marvel sale at Comixology? I love the Image Sale and the Dark Horse sales.

They had a linewide Marvel sale in February, B1G1F. It was their first, and never one for DC so far, afaik.
