Twitter has been dabbling in timeline-based purchases already, and its latest effort will boost commerce-driven tweeting. Twitter Offers serves up discounts from participating retailers that you'll be able to grab right from the tweet -- so long as you've linked a credit or debit card to sort the funds, of course. To leverage the deal, all you have to do is pay online or at a physical location with the same card. The social network will charge companies to promote their offer-packed messages, and could later opt to bill for every deal that's claimed according to Re/code. Twitter acquired online coupon/payment startup CardSpring earlier this year to power the offering, and discounts will begin appearing as early as today. Perfect timing for the Black Friday scrum, no?
