As usual, Google Play Books may be available for a country and unavailable for another. If so, try to set your Google account to be a US one, and try to follow on doing that for any other hooks if they are unavailable. Other than that, the collection of discounted to free books are there in great totals. The one most recognizable is the Batman comic issue, with the least worthy being the MLP comic book (MLP? Ahahahahaha!)

Try to get em' fast! They're not going to stay forever.

JamesBond007: I'm not interested in this offer, but I've tested it by using my other Google Account (my main one is blocked to Poland) and a VPN set to the UK. Everything worked fine, I've got Skylanders #1. Unfortunately, not without side-effects. My second Google Account is now blocked to the UK (I'll likeky create a third account for the USA). However, there are also good news - I can access the UK Play store without using a VPN!
