Digital copies of Jason Aaron's Thor run from 2011-2017. Each volume is ~400 pages, so at $11 ea this is definitely good value for money. Physical editions are ~$60-$70, so definitely cheaper to purchase this way. I believe these volumes are usually ~$35 for the digital editions however they aren't accessible on CamelCamelCamel so I could be wrong.
$44 total for ~1700 pages of Thor comics if you stick with Vols 1-4.

Volume 1 is an absolute killer and what originally got me into reading comics. I believe some of the later volumes are relevant to the recent Thor Love and Thunder movie but I haven't read them so can't confirm?
These must be read through the Kindle app (or Comixology app?), so this is probably only worth it if you have an iPad or another device with a decent size screen to read off. Definitely possible to read on a phone, but
They used to go on sale for $4-5 but that was before the 'new and improved' comixology screwed everything up. These days sales aren't are good and I've bought barely any comics.
