Amazon offers the Starbucks Doubleshot Espresso + Cream 6.5-oz. Can 12-Pack for $13.49. Add it to your cart via Subscribe & Save and the price drops to $12.82 at final checkout. With free shipping, that's a buck under our mention from two weeks ago and the lowest total price we've seen. (It's also $4 below what you'd expect to pay at your local Walmart.)
Note: Be sure to cancel Subscribe & Save once your order ships to avoid being billed for subsequent shipments.
