Twitter and American Express team up to let you purchase with hashtags

Looking to make a new purchase from Amazon, Sony, or Xbox? How about making your purchase through a tweet? A new partnership between Twitter and American Express will allow users to connect their American Express credit cards through the Twitter site and then make purchases from select retailers, the Wall Street Journal is reporting.

Items up for sale through Twitter include American Express gift cards, Amazon Kindle Fire tablets, and Donna Karan jewelry, according to the Journal. Twitter has not yet responded with a comment on the partnership, but a press release from American Express explains how the hashtag purchases will work:

“American Express Cardmembers who sync their eligible Cards at and tweet special #hashtags can buy American Express Gift Cards and products from Amazon, Sony, Urban Zen and Xbox 360. American Express’ proprietary Card Sync technology powers the experience. Card Sync first launched on Twitter last March to deliver couponless savings to Cardmembers who tweet special offer #hashtags from merchants.”

Most of Twitter’s monetization efforts so far have come through marketing and advertising, such as promoted tweets which now cost up to $200,000 a day, but this partnership that allows purchases through tweets could move the company toward e-commerce opportunities as well. In March, an American Express partnership allowed consumers to link their cards and Twitter accounts to then receive coupons through the service.
