Daily Deal Aggregator (Yipit clone)

I have a website ([login to view URL]) that uses to [login to view URL] API to aggregate deal content and notify users (via email) when a deal that matches a keyword they have entered becomes available (keywords are checked against deal title, description and tags). I want to move away from using the [login to view URL] api and build my own international daily deal aggregator. [login to view URL] interface and functionality will remain the same. The aggregator must pull in all related deal content (image, price, time remaining, % saving, link to purchase, etc..) and have a backend to easily add new deal sites and affiliate links. There is an existing backend to view the keywords users have entered, their location and email address. Aggregation can occur using whichever methods you deem appropriate (rss, web scraping, etc..) but must leverage affiliate links whenever applicable. Please let me know if you have any questions.
