I tried posting a deal for a company I now can't mention because HUKD say it's not allowed because:
1. They don't advertise a phone number. Not that uncommon as a lot of companies successfully trade online via email for pre and post sales support.
2. The didn't put the address on the contact page although the contact page contains all the email and fax details plus the terms and conditions includes full address details (don't think they clicked that far).
3. They looked it up on google maps and the registered address looks to be residential ! Guess that means the majority of eBay home run stores are completely unprofessional as well.
