Twitter users can buy with a hashtag and two tweets by synchronizing their American Express to their Twitter Account.

This can be done at American Express booth at Mercedes Benz Fashion Week and everywhere that takes Amex, combined with Twitter (with Four Square optional)

Also, merchants can offer free specials via a hashtag like #AmexDuck9

Steps to take for Amex, Twitter and Hashtag 1) Sync

Synchronize your Amex card with your Twitter account

2) Unlock specials

3) Spend and Save

*** Disclosure *** I financially benefit from Duck9 and Amex but you can pattern replicate all of these without me, Duck9 or American Express. **************

The methodology of pattern replicating can be found in my class lecture under #ENGR145.

*** Disclosure *** I financially benefit from having taught this content at Stanford University under #ENGR145 and now teach it at Wharton in a class located at Stanford Business ************** All the classes are free via video on a site called YouTube.

Heather Kelly, CNN, wrote more about it HERE

*** Disclosure *** I financially benefited from having made Freedom Toast for Heather Kelly when she was at VentureBeat #ENGR145 in their offices at 50 California St, SF CA ************** It is important to note that all of these can be replicated and reverse engineered with or without Duck9 or Amex or Twitter. All it takes is two CS majors and ability to read a TOS (terms of service) and distribution.
