*On that note, definitely expect a post stuffed with Black Friday/Cyber Monday deals as I see them! Hopefully I won’t be too busy shopping for bargains myself. 
Does Turtlehead ship worldwide ? I´ve found no shipping option. Does shipping cost in general cost 6 euro ??
Yeah they ship worldwide, its 6eur for one shirt, 9eur for two or more it seems (to Germany at least).
As for the option, just add something to the cart it automatically quoted the price for international shipping for me, which was still there through the paypal process.
Thanks for the fast answer. I like the “Same circus diffrent clowns” tee.
