It stinks that you need to buy the DDC package but if you have a lot of domains at Go Daddy, you should. Your rep is NOT allowed to give you the prices that you get with DDC. You will pay about .40-$1.15 (approximate) per domain using your rep. Your rep won't tell you this unless you pointedly ask the question. As a 'special' customer they make you think that you are better off using a rep. That used to be the case, until Go Daddy Bob (Parsons) figured out another way to nickel and dime you between 'Go Daddy Girl' interviews and toting up expired domain sales. You will also do better buying this thing rather than messing with their reseller program unless you'd like to collect some names that Bob will make the real money on when they expire and he gets to sell them at TDNAM.
You may also do better finding another registrar. Unfortunately, they all seem to be crooks in one way or the other. I went to one other large registrar and then went to transfer some names. The prices that their rep had quoted me verbally turned out to be for the first year of new registrations. He didn't mention that till I asked about the 'problem' so for now, under diress, its DDC for me. I can't get that registrar or another that I asked about quantity rates to even answer their support or sales department emails. To be fair, Go Daddy is above average on that but when they find out that you are a 'special' customer, everything shuts down till they can find a rep to allow customer service to begin for you.
One more note: You are supposed to get the very best prices without using coupons with the DDC program. Like so many things with Go Daddy, that isn't true. You will get .BIZ registrations and renewals for $1.00 less using cjcbentld. There may well be other anomolies. I brought this up to Go Daddy but they could care less as DDC members are just paying to pay an extra $1.00 and that's sure OK by Bobby P!
ALSO, if you do sign up for DDC, use the promo code CATALOG1 to buy it. It will save you $20. This code also works for $20 off $75 or more for 'Investor's Edge' purchases as of now, at least.
