Lots of talk about pirating comics, so some tips on where to pick up comics if you’re genuinely stretched:

Webcomics
Legal free comic sites
Humble bundles
Comixology sales, on all the time
Marvel Unlimited, a great all you can eat subscription service

Of course there are always charity shops as well (thanks @rowenaaitken) and of course LIBRARIES!
