VeriSign and Neustar have decided (again) to raise prices for .com, .net, and .biz respectively. As a result, some domain registrars will raise prices too.

For example, Namecheap has announced on their website that on January 14, 2012,  the price for a .com or .net registration or renewal will increase to $10.69, and on January 31, 2012, the price for .biz will increase to $10.26.

However, you can use a Namecheap coupon to save some money.
