I mean that I buy domains (as a reseller of a registrar), and $26 is the whopping discount (over the $30/yr. charged by .nu itself on their site). I've always wondered if the $10 nameserver DNS charge would apply to me as well, but other than that, the point is...
By the time you get done with cc processing fees and adding a bit on the top, the price is likely to be as much, if not more, than nunames itself. In other words, I'd be surprised if there are bargins around (example: registerfly shows $29.95)
