The prices are $3.44 and $5.74 for me (when logged into Amazon US). That's a nice +250% price hike for us Europeans!

Came here to say this and I accidentally bought the basics version instead of the more extensive one.

Oh well, I really liked the YouTube videos so the author more than deserves it. It's just that those obvious price hikes get under my skin especially for e-books. Or is it that Amazon includes any taxes they have to pay to the EU in the price?

Amazon is paying VAT in the EU, but the last time I checked, the tax wasn't quite in the hundreds of percents. This is just Amazon taking extra profit because they can, and the author is only getting paid based on the $0.99 and $2.99 price points.

2.99 euros on amazon.fr for the extended one, looks reasonable ( $2.99 + VAT ).

I was not logged in to Amazon when I first checked the links. The prices when not logged in were 2.99 and 4.99. When I logged in, the prices became .99 and 2.99.
