Since I published the Math Guide at the end of last year, I've been looking into ways to sell it outside the US. As an independent author, though, I don't have very many options. I basically have to wait until the services I use (Amazon and Google Play) expand their reach into a new country, and then I can enable sales in that country.
Please understand that if my book isn't currently for sale where you live, it's not because I don't want to sell it to you, it's just that I don't have the capability. I'll make it available there as soon as I can.
Here's the current list of non-US Amazon sites that sell the physical book:
And here's the list of countries in which the ebook is available through Google Play (I don't know how to link to different countries' Google Play sites, but if you go to Google Play and search, the book should be there):
- Brazil (NEW!)
- India (NEW!)
- Russia (NEW!)
- South Korea (NEW!)
- United Kingdom
