For information Teespring tried to send the shirt 2 times (to France) but I never received it from the last campaign in august, both were lost somewhere...
They have refunded me yesterday and said We're working on perfecting our international shipping delivery, but unfortunately there are still occasional hiccups when we ship abroad.
Isn't it possible to put it also in zazzle (the new negative feedback design) ? I never got issues with them.
