Godaddy is possibly the biggest domain registrar in the world. The general, non-coupon, prices are decent but after adding whois protection do not really compare to NameSilo or Name Cheap.
GoDaddy changes coupon codes regularly and will occassionally have unbeatable deals with their coupons so check back regularly for domain deals.
Free Whois Privacy - Best Prices
I use NameSilo all of the time, even for this very domain, as they generally have the best prices overall and with the coupon code below you can get a further $1 off any domain.
For everyday pricing that cannot really be beaten, especially with the free whois privacy, I would recommend NameSilo all day long.
