Deal Aggregator - Integration of cobone.com & livingsocial

we are looking to integrate ( scrap ) [login to view URL] and [login to view URL] for our dealaggregator we have already tried scrapping these sites but was not succesfull. Please find the details of the error below Normally, for scraping the content, two methods are used, 1.file_get_content [login to view URL] [login to view URL], While we crawl this site using those two methods, instead of getting the respective file content, we get empty data. [login to view URL], When we scrape the link of any deals or any city, its redirecting to the subscription page. Also it has three levels of subscription steps, thats also a problem. It is not allowing to take the contents. If anyone is able to scrap these websites please let us know.
