The EU has changed their laws (GPSR) for companies outside of the EU to now require a designated "responsible person" for safety and compliance located within the EU, along with other compliance requirements effective Dec 13th.
Physical and digital products will no longer be for sale to anyone located inside the EU from my shop, as I don't sell enough to EU countries to justify the expense and legal hoops of hiring EU personell and certifying compliance.
EU residents will still be able to purchase my books via other "giant" retailers who will certainly be able to be in compliance with the new laws.
I'm sorry for any inconvenience or upset. This change is effective immediately.
