It’s actually not a shipping issue for Black Cat Bite People Hail Satan Tshirts. I’m a stickler for following the rules and the GDPR (EU law) says that if I am selling into the EU I need to list my physical shipping address on my site, not a PO Box. I run my little business from my home, so that address is my home address. While I don’t think it would be a big deal, other members of my household feel differently, so out of respect to them and in the spirit of following the law, I do not ship to the EU from my site. Having said that, I have on occasion accepted G&S payments via PayPal and shipped to EU folks, and I ship pretty much everywhere when I run a Kickstarter, as that is a bit of a gray area.
