We recently heard the $1.99 domain offer from Yahoo! Small Business may be ending soon. When the offer ends, the price of a domain will go back to $9.95.
I recommend that you take advantage of the offer now while it lasts. Click on the link below for the offer.
Or you can always buy a Yahoo Web Hosting Plan and get the domain for free.
will keep you posted on when it will end but think the offer will be over by the end of the year.
