I thought of an idea, and I dont know if it is feasable.
What if hotukdeals setup a free telephone number with an automated answering machine which is checked by the admin say once every couple of hours.
Reason being, many of us tend to find really good deals when out and about in the supermarkets and malls yet we are far away from the computer to tell everyone about the deal. So since most of us nowadays have free minutes on our mobiles, may be you can submit a deal via ringing a free phone number.
Just a suggestion.
