Starting from today(well not today anymore), Comixology (a digital comics distributor) is offering 700 issue #1 Marvel comics for absolutely free. This stuff ranges from their 60s and 70s originals to the Marvel NOW relaunch that started last fall.
Now, you do have to sign up for an account, but the convenience of reading this stuff on your smartphone, computer, or tablet more than makes up for it.
This is a great opportunity for new readers looking to get into comics as well as old readers. So, go ahead and buy some shit!
