There are a couple factors that determine availability of Add-ons in a country.
First, Azure continues to expand which countries are supported in the Store. Currently most of Europe is supported.
Second, Store partners select which of the available countries from which they wish to allow purchases of their Add-on.
Which Add-on were you interested in purchasing?
