American Express has long advised customers not to leave home without it. Now, it may be telling you not to sign-on without. The Wall Street Journal reported on Monday that Twitter and American Express are partnering to allow Twitter users to buy directly through the site.
Cardholders will be able to link their card to their Twitter account and use a simple hashtag trigger to make a purchase. The WSJ says neither company will discuss terms of the agreement just yet, but that Twitter hasn't ruled out taking a percentage of the e-commerce sales in the future.
