The landing page should have a logo (or placeholder), social icons, a search box, and list of deals.
Some key elements to work into each deal are an image, title, description, social icons, and I prefer the image hover call to action seen on Fancy.com and portrayed in the attached image, something along the lines of "Get Deal". However if you work a button into the content area I am ok with that as well.
Some optional items are specific text fields for Expiration Date, Low Price By: $$$, store logo (Kohls, Amazon, Best Buy).
Read more / read less - In order to fit a sufficient amount of copy for the description I incorporated a "...read more" which when clicked expands the content area up over the image. A "...read less" link closed the expanded window.
Noting this as the page can have interactive elements even though it is meant for click through.
