Update Jan 2019: I have now figured out a way to resolve this issue. Every person who purchases a course from me also gets access to office hours with me. I have left the older post below for reference if you have already stumbled on it.
If you are a resident of EU, you cannot purchase any courses or apps  from my Thinkific course website, located at https://courses.miningbusinessdata.com
This is because I am not yet clear on what the VAT/MOSS requirements are (and neither, it seems, are the folks who create these laws), and I am not interested in adding more overhead to my business by registering whatever to whichever by whenever.
So I have selected a service called Gumroad to charge EU customers as they handle the VAT/MOSS compliance for me. Since they take a cut from the transaction compared to my current course platform (plus it requires me to do a bunch of manual work), I am passing on the fee to you.
If you reside in the EU and you are interested in purchasing one of my courses, please head over to my Gumroad page, look for the appropriate product and purchase it (all the instructions are on the sales page).
As you can see, nearly all courses include an extra $6 fee - usually the nearest multiple of 5 which includes the extra charges. (I don't charge the extra fee for the higher priced bundles - which means I eat the cost - as the prices are already substantial).
Suppose you wish to purchase my Intro to Dialogflow course. Currently it is priced at $29. You can see from the list above that there is a product for "Payment for $29 course" which is what you will buy. Once you purchase it, tell me which course you want to buy via email. (In this case, it will be the "Intro to Dialogflow" course).
There is a small silver lining in this. Gumroad is one of the coolest companies you will ever come across. So you will be supporting them, which isn't such a bad thing. If you wish to buy a course bundle priced at $99 or more, you can still do it. These bundles include live training.
