.FARM is a naming solution for your farming-related websites.

The .farm extension is a perfect choice for farmers, suppliers, analysts, researchers, buyers, storefronts and all other organizations within the farming community. Any business or individual may register a domain name with the .farm extension.

At the time of this post Google (beta) domain name services was the cheapest offering for .farm at $30/year.
Godaddy was $39. Aplus.net was $35. Most were over $35, so shop around! Also beware of Godaddy’s upcharging, you really just want the domain name. Especially if you don’t want hosting, private listings, email, etc.
