While googling "namecheap coupon," a Godaddy ad showed up. I know many aren't fond of Godaddy, largely due to their terrible Super Bowl commercials. Oh, and the SOPA thing, I suppose...
Anyways, it's a cheap domain option for testing websites before they become worthy of renewal.
If the link doesn't show a yellow box on the GD page saying "SPECIAL OFFER! .COM just $0.99*! Additional .COMs just $7.99* per year!", then do a Google search for "namecheap coupon" and it should show up.
>Make sure to change the Term from 2 years to 1 year in the cart to see the discounted price.
