$1/1 Starbucks Refreshers Coupon

Check out this Starbucks coupon! Just head on over here to print a  $1/1 12oz can of Starbucks Refreshers beverage coupon. Since this is a new product, we should be seeing lots of sales. Has anyone seen these yet? I went to Target today and didn't see any.  If you know the price of these, feel free to share in the comments.
(Thanks, Coupon Pro!)
