Walmart and Facebook are teaming up for a new initiative that adds 3,500 store-specific pages to Walmart’s presence on the social network.

The initiative is meant to increase the mega-retailer’s interaction with local communities — and compete in an increasingly crowded Web-based retail environment.

The pages will provide customers with product updates, sales and deals and information about in-store events.

Walmart has been working to increase its online presence and has seen some success with its streaming video site, Vudu. As the Post’s Dominic Basulto pointed out in August, the retail giant has been working carefully to pull together innovations from social networking and mobile as well as creating @WalmartLabs, a Silicon Valley-based group focused solely on social media commerce.

The initiative will also give eager shoppers the chance to map out their holiday shopping by offering downloads of maps of local stores for Black Friday.
