I see their prices are pretty tempting ,Is it the best or where is the catch?[/align]

Generally the price of a domain per year is around $6-9, so with the discount the price sounds about right.
Although I haven't registered with yahoo, I think should be a pretty safe and good deal.

If you are mindful of any catch, read the TOS carefully.
