For all bloggers and webmasters, Godaddy has released a special coupon code 99BUYCOM using which you can register any .COM domain for 99¢.
I personally tested this and found it to be working. Although it is valid for 24 hours, I am not sure how many hours before this coupon code has been released. So hurry up! Best of luck! 
Thanks Deepak for tip!

Update: Check Dave’s comment below….
Actually the code is good for the first 5,000 redemptions or until 5/1/09…whichever comes first.
Applies to the first year only of new or transfer registrations. This offer may not be used for renewals, bulk registrations, premium domains or Sunrise/Landrush domain registrations. Limited to one order per customer, expiring after 5,000 redemptions or on May 1st, 2009.
Discount will be reflected in your shopping cart; cannot be used in conjunction with any other offer or promotion. Customers may not use gift cards or PayPal® to redeem this offer.
Your discount will be applied in your shopping cart.
plz…notify these hot offers in future..
The offer is very tempting..but the sad news if they don’t accept paypal..
Apart from that one more good news is dreamhost giving away hosting for 10$/yr + 1 free domain.
its dead……
Yeh – the code doesn’t work any more. I guess it reached its limit of 5000 orders.
If anyone finds any more – pls post it here..
Cheers
I was gunna post that this was expired already, but got beaten to it
Here are my collected Go Daddy coupons:
emma1 = 10% off any order, no minimum spend
emma2 = 20% off any order over $30 or £25
emma3 = any .com domain for $7.49 (works on new domains and renewals)
emma30 = any .com domain for $7.49 (works on new domains and renewals)
emma35 = any .com domain for $7.49 (works on new domains and renewals)
They don’t expire, and can be used on most orders, so hopefully someone will find them useful.
@ Shanna
Your codes seems to be your affiliate code. I really wonder how Rahul,accepted your comment?
@Harsh
“emma” series promo codes are very popular and I think they are in circulation by GoDaddy itself!
Also these promo codes are adding value to this post because promo code specified in post is expired.
99INDY Is the new promo code for .99 domain names
