Setup a twitter account and post a couple of bargains per day which your site has found - that could then drive traffic to it. Find twitter 'lists' that people have created and see if there is a money saving / bargain list and ask to be added to it. Even better, start your own list and request others to join it and then publicise it. You should then get other accounts following you and they may RT :)
