Dont know if anyone has figured this out yet...

One way to save money with godaddy ( with no spend limit ).

Procedure :

 

• find a domain
• add it to cart
• proceed to checkout
• Get onto the final screen (last step before it uses your creditcard / paypal)
• DONT pay for the domain.
• DONT logout of GoDaddy.
• Close the browser or website...don't revisit the site until you get the email
• wait
• wait some more..
• you will receive a "Complete your order and save 30%" email.
• Use the coupon code provided in your email.

Seems like its worked twice this week for me, only purchased 2 domains on separate days.

Would be good to know if this works for someone else.
