I want to sell digital Downloads ... I suppose I could use MarketPress ? But I dont know if it can handle EU's taxes ... As a reminder, ALL SALES made TO a european customer must include the VAT of this customer's country ...
So if your site is based in the US (or any other country outside EU) you still have to charge EU's VAT on your physical product AND/OR digital downloads ... Otherwise you might get in troubles sooner or later.
Here is the law since January 2010 : http://ec.europa.eu/taxation_customs/taxation/vat/how_vat_works/e-services/index_en.htm
In my case, I am based in France, so I must sell including French VAT to all EU's Countries, and excluding VAT dot the countries outside EU.
