Digital Comics Sale + Extra 50% off with Code eg. Graphic Novels $1.50 USD (~$1.98 AUD) @ Dark Horse

Dark Horse Digital have a sale on comics that are more for the younger reader amongst us. Or young at heart :)
Some great bargains especially when you stack it with the code MEMORIAL for the Memorial weekend in the US. I can only assume this ends today or tomorrow so be quick.

Some of the titles on sale include:

Usagi Yojimbo Saga Volume 1-7 $1.50US/~$1.98AU each with code
These are 600 page volumes for under $2. Collect all 7 volumes for under $15AU. I've only linked volume 1 but it will show the next volume on the page. Alternatively find all the volumes on the main page.
Usagi Yojimbo Saga Legends $1.50/~$1.98AU
This is a companion book for the above mentioned Saga Volumes. If you are getting all 7 volumes you might as well get this one as well.

Groo: Death and Taxes $1.50US/~$1.98AU
Only about 100 pages and there are 6 other collected volumes of Groos adventures.

Astro Boy Vol 1 and 2 $1.50US/~$1.98AU
Each individual volume is about 200 pages excluding the first book which includes 1 & 2. 12 Volumes in total.

The Adventures of Dr McNinja Omnibus Volume 1 $1.50US/~$1.98AU
The title sort of snuck up on me. Its a web comic so maybe check it out here before you decide.

I'm gonna go Usagi Yojimbo. Great bang for buck.
Note that Dark Horse Digital works like Comixology/Amazon. The comics are not DRM free and you need to either read the comics online or via the app on iOS or Android. From the FAQ you can only read them offline via the app.
