I believe this kind of service would work better as an email newsletter. I wouldn't mind receiving a weekly/biweekly email with hot deals relevant to my interests. I think you should push deals to the people (i.e. email) instead of pulling people to the deals (website). A bare minimum would be an RSS feed although I think email would work better in this case.
I'd rather see this as a newsletter too. In fact, please reach out to me when it is available. Thanks.
Cool. I'll reach you at your email once I get it up. Thanks.
