There's no such thing as an eNom coupon code if you have a reseller account. All of the promotions are open only to direct ETP's who register directly with eNom via email or phone to have their pricing adjusted. If you have a subaccount, it's up to your ETP to adjust your price; but again there's no "coupon code".
Codes are only applicable at eNom's retail site, eNomCentral; there are presently no promotions there.
Radioz, eNomCentral was only set up so owners of domains purchased through resellers who have gone out of business (or have had their status terminated like RFly) can manage their domains. Unlike Wild West/Go Daddy, it does no direct marketing to consumers. If eNomCentral was interested in retail business, do you think domains would be priced at $29.95?
As for your ClubDrop purchase, you don't mention whether the name was originally registered under the eNom cred or not. If you PM me with the details, I can pass it on directly to someone who can track it down for you.
quixergeo, your account should list what problems were encountered in your transfer under "Transfer Status". It's possible you did not unlock it, or respond to the losing registrar's confirmation email. PM me with the details and let's see if I can help you.
