Is there a free way to see international android app offers on the google play store and other international offers for that matter? Or do I need to get overplay?
You'll need a VPN service such as Overplay, it's a standard indispensable tool for most affiliate marketers.
Overplay is great, and its very cheap!
You can use a free proxy from HideMyAss's list et al, but Overplay is considerably less of a pain in the ass.

If it helps - hola on the desktop for google chrome works like a charm.
