MANILA, Philippines - American Express has introduced a new social commerce experience that turns Twitter #hashtags into purchases in a unique and seamless way. American Express cardmembers who sync their eligible cards at sync.americanexpress.com/twitter 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 year to deliver couponless savings to cardmembers who tweet special offer #hashtags from merchants. The $25 American Express Gift Card can be purchased using a synced American Express Card for only $15 by tweeting #BuyAmexGiftCard25 (quantities limited, offer expires 3/3/13, limit one per cardmember). American Express cardmembers can sync their eligible cards with Twitter to purchase products and access content, offers and more. Cardmembers already synced with Twitter for offers need to add a few more details, including their billing address, for product shipment.
