Don’t use Marcaria as a domain registrar
(I don't usually take to my blog when I feel wronged by a company, but after all it is the traditional recourse when appeals to customer service fail. Feel free to skip this post if you aren't domain shopping.)
I registered a domain with Marcaria last year because they were one of the few options for .ps domains. (Normally I would have gone with Gandi or NameCheap.) They were offering, and are still offering, $49 as an "annual price" for .ps domains. That's their wording. You can see it on their live site as of this moment, although of course they may change it after publication.

And then yesterday I went to renew.
