Pepsi offers a Pepsi Next 2-Liter Bottle for free when you complete a short form. (A coupon will be mailed to you.) That's the best offer we've seen for Pepsi Next. (We saw a free can of Pepsi Next for Sam's Club members only last spring.) The coupon is valid until March 31. Offer expires after 1,000,000 redemptions or on February 4.
