During April and May 2014, you can register a new .CO for one year for half price: $16.50 instead of the regular $33.00 at A rates.
The timing is perfect for this promo: .CO, technically the ccTLD of Colombia, is becoming increasingly popular in the tech industry as a generic extension. Google has even confirmed it will consider it as a GccTLD for the purposes of indexing and SEO [Wikipedia].
.CO domains are available to all, with no residency restrictions. For more information or to register a domain, see the .co TLD info page.
