Have you thought about creating "how to" videos for your products? This will give you something helpful for the communities to promote within your social presence.
You should definitely think of ways to add new content (other than products) that will help you stand out from every other website that is selling the same products.
You could also look into broken link building strategies as a source for identifying content you can create.
