OK manga fans - Comixology has a ton (273 to be exact) of Volume 1 e-comic collections for $0.99 each. So much goodness, I encourage you to browse the entire list but some recommendations (both obvious and not-so-much) below
Most, but not all, are also available on Amazon but no single landing page
The slickest deals are for Ghost in the Shell, Negima! and Love Hina - all amazing series
Normally, Comixology gives away 4 free comics a month.
But I think they're doing something special since everyone's staying at home due to COVID-19.
There seem to be literally hundreds of books I've never gotten before! https://www.comixology.com/free-comics
