24x7 Support - 99.9% Uptime Guarantee
I found this to be a great selling point on their support. From HostGator's website, "Every web hosting plan comes with a 45 day money back guarantee, 99.9% uptime guarantee, and is fully guaranteed by the owner himself. If you ever have a problem with regular support just ask that your ticket be assigned to Brent and he will personally take the time to give you the VIP attention that you deserve."

30 Money Back Guarantee - No Contract
