Coupon is TESTANDCODE
I had already used it before realising it was one or the other, honestly its one of the better TLD’s IMO, too bad Cloudflare doesn’t support it yet.
Edit: I should have mentioned, you have to make a tentative payment of 1 USD, which is reverted.
Oh thanks for this! I’ve been considering transferring all of my google domains to them, but wasn’t sure if I wanted to pull the trigger yet. Now I can test them out.
