Many Current GoDaddy Coupon Codes are a Bust

Wow, the $7.49 coupon codes aren't working for my renewals; not even the new ones for 2011, such as FAN3.  That's unfortunate because I've always been able to get a good discount on a single domain.  Now GD wants me to purchase at least $30.  Well, that's not gonna happen today.  I have one other to renew, but I'm trying to save money at the moment, not spend it all.  I guess I'll have to settle for this code - gdz1112a - I found through LiveCodes.Blogspot.com that takes the price down to $8.39.  Strange that RetailMeNot.com didn't pull through for me on this one.
