This is a good project; please keep at it. I think it might benefit more people in NA compared to the rest of the world. I did a quick search for "Flask Web Development", which I purchased one week ago on Amazon for AU$56($35). But it looks like I could get a used copy from AbeBooks (a result of a search on your site) for $8, the catch, I would need to pay $35 for shipping to Australia. If I had been in the US, I could have gotten free shipping or under $10 shipping which would make it all worth it.
