Google Apps for Your Domain added an option to buy a domain from eNom and GoDaddy.com for $10 a year. You can only buy .com, .org, .net, .biz, .info domains using Google Checkout.
"When you register a new domain as part of the sign-up process for Google Apps for Your Domain, we'll work with our partners behind the scenes and automatically configure everything so it works with all of the services available through Google Apps for Your Domain right out of the gate. We also give you full control of your domain settings, so you can use your domain for other services not provided by Google," explains the press release.
While the idea is OK, you can buy domains cheaper than $10 per year. It's interesting to note that Google is a domain registrar since 2005, although it has never used this status to sell domains.
