Twitter extended it’s partnership with American Express and building on the campaign to tap into support for local businesses with the rollout of Twitter Promoted Products. It’s a pay per-click model which can be limited by daily spend so there will be no surprises.

The video is one of the nicest product videos I’ve seen. It’s clear, concise, and speaks directly to the potential customer. The video assumes a certain familiarity with twitter so will attract only the well-versed merchants that will get the most from the program. It also has been pointed out that the video shows a bias for iPhone users as all the audio cues are prom the iPhone.

Interested? Registration is open to American Express cardholders and merchants today and if you get picked, they’ll throw $100 your way to get started.
