For those that need it, here's a link to the comics at Comixology. You can buy and read them online through the service!
For further information, I highly recommend buying the "Collector's Editions". Each one comes with four chapters, a bonus comic that you can't get normally, and some awesome alternative covers. Plus, it's the same price as it would be by buying each comic individually (give or take three cents).
Currently though, there has been a long wait between each Collector's Edition release, and Vol 5 just came out this month, so it might be best to just buckle down and buy the rest of the comics in non-Collector's-Edition format if you want to read them ASAP.
EDIT: Actually, after looking, it seems that Vol 5 is far more expensive than the previous four volumes. :S Not sure if it's because it just came out this month, or if it's for other reasons though.
Dude, you can buy e-versions of the comics. They're a little cheaper than hard-copies, but you don't have to worry about shipping costs or road trips.
I bought the first volume through Comixology, though I haven't gotten around to reading any more than that yet.
Well, I watched Bee and Puppycat on a tablet with Opera VPN... and on iOS you could get that or TunnelBear. It works.
