众所周知,雅虎曾经有一组每年仅1.95美元的域名优惠码，当年让很多朋友为之心动。但后来雅虎涨价了，提高到了每年3.95美元，而且称这一促销将在今年年底结束。现在看来，各商家的低价促销让雅虎也坐不住了，不再保持日前的强势态度了。日前，他们家放出了一枚1.99美元的优惠码，适用于新注com、.net、.org、.biz、.info和.us等。

优惠内容：新注册域名首年仅1.99美元，适用于com、.net、.org、.biz、.info和.us等后缀。

小荷塘最近有一个在Godaddy的域名要到期了，打算继续使用，却发现续费价格竟高达15刀！找到一个31%的优惠码，发现仍要10刀才能续费。
上网查了一下，找到一家小域名商NameSilo价格还算便宜，NameSilo官方续费.net域名的价格为6.99刀，用上优惠码“TRYNAMESILO”以后，价格减去2刀，最后以4.99刀的价格，完成了续费，还赠送了免费的Whois隐私保护，十分超值。
与此同时，小荷塘还发现，NameSilo家新注册.net域名的价格也是6.99刀。也就是说，如果想注册一个新的.net域名，用上优惠码以后，也只需要4.99刀。
NameSilo优惠码：TRYNAMESILO
