Bad week in terms of GoDaddy coupons unfortunately, only 4. Not sure whether they work worldwide or only for customers from the US and Canada. Didn’t use any of them myself, so I can’t guarantee they’ll work.
Since there are only 4 discount codes this week, testing them won’t be all that time-intensive, might be worth giving it a try if you want to hand register or transfer a domain.
One of them should bring the price down to $0.99 and three of them should bring the price down to $1.99.
First, here’s the coupon which should bring the price down to $0.99:
And here are the three which should bring the price down to $1.99:
The most helpful resource for those of you who want to find GoDaddy discount codes as well as coupons for other registrars is Namepros.com in my opinion but be sure to also follow all of the important registrars via twitter since they frequently tweet about new promotions.
