"Like" Skinny Cowon Facebook and get access to a printable $1/1 coupon. The page states that it is not good on the ice cream cups but the coupon says "on any one (1) The Skinny Cow Product." and doesn't say anything about excluding the cups. (It should be good on the single serve bars though.) The one I printed today doesn't expire until 1/28/11.
*The coupon link can be found under the Fan Exclusives tab.
