CrowdSourcing- The New Social Media Mantra to Sell Better

Should be called "crowdSelling" or "crowdarketing", because it's basically marketing outsourced to customers for pennies. Seems, like a good idea, though.

It's basically an "affiliate marketing" under new name. Only this time you get discount instead of real money for bringing in customers. Although this should be better than aff.mark., since you are interested in buying that product, not just advertising something you never tried (like so many aff.mark's do).
