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.
I’ve used gandi for about 10 years as well, but they lost me to porkbun with their recent not-so-well communicated price increases (including dropping the small free email mailboxes)
I didn’t feel like they were too badly communicated, but maybe that’s just means my standards for corporate coms isn’t very high.
I’m currently testing https://www.migadu.com/index.html as a replacement - $19/year seems like a pretty good deal.
