Question regarding sites like holidayguru

Hi,

I’m working on a travel niche site and I’m interested in adding hot travel deals like the holidayguru site. Now I have a hard time believing a site like that searches for deals manually. It must get that info from somewhere, no?

Now that’s my question: where do they get their information from?

Thanks in advane!

Based on the amount of posts they do of *new deals* I believe they actually do search it manually.
