While GoDaddy is biggest and most trusted registrar, I recommend to buy domains only from them. Registerfly gave a good lesson, what could happen if you run a risk and try other registrar (even if it looks good enough).
And even more – you could save money. There are number of promo codes, which give you some savings. Since friends and colleges keep asking me about them, I’ve decided to post them here and keep updating.
Update June 1, 2010
No one of below provided codes worked, except gdbb776 – $7.68 $7.99 /.com renewal – after icann price increase on July 1, 2010.

gda347d gave $7.17 price for .net renewal and $7.66 for .com one. Should work for new domain registrations too.
OYH7 – $7.49 +0.20 ICANN fee .com domains (and renewals too) – sometimes works for other domain extensions too.
goaz006c – 6.99+ICANN fee for new .com domain registrations – works for multiple year registrations (+ free whois privacy protection if you register 5 new domains at once)

Old, but usually working codes:
hash3 or OYH3 – pay $7.49 instead of 9.99 for each .com domains. If you pay for more than 1 year, $2.50 discount applies for each year.
OYH2 – $5 discount for any services, if total order amount is over $30 (best to use, when keeping total amount is ~ 30$ )
OYH1 – 10% discount for any purchase at GoDaddy (not only domains – includes all services)
