We've had some great discussions regarding auto sales finding a viable platform on a variety of social media platforms.  My contention, fully based on dozens of Facebook campaigns I've actually directed, is that only items with low cogs and a 10x markup can succeed.  This includes factoring in "Save-a-Sale" strategies, upsells, continuity, and bulk buy pricing.  I've never seen anything that sells for over $399 have long term success on FB.  I'd love to hear other folks thoughts!
