Watch out, Pinterest. Facebook may be dishing out a little bit of competition. In case you were a little bit off the grid because of the Columbus Day holiday, on Monday the social network began testing a new feature called ‘Collections,’ which allows marketers to add “Want” or “Collect” buttons to news feed posts about products. According to TechCrunch, these posts save and share products to a “Wishlist” on Facebook users’ profiles, and feature a “Buy” button that users can click on to make purchases offsite. Facebook is testing the feature with 7 retail partners — Pottery Barn, Wayfair, Victoria’s Secret, Michael Kors, Neiman Marcus, Smith Optics, and Fab.com.
