The current item(s) promoted in social media could be at the top of the page and represented with either a clickable photo or button. It should be relatively simple so updating would be fast and easy. Below current promotions, standing items or links to product categories might make sense.
Below here could be linked photos to products, specials, etc. with any layout and design that is desired… here are a couple placeholder products as examples.
We could also link to categories of products or link to products for specific occasions, like birthdays, sympathy, etc.,
Links could be buttons or photos or simple graphics.
