Perfect.
Kevin gets to publicly announce that he likes something, and for anybody who is listening, they're also notified that the product happens to be on sale. I don't see how Kevin has been slighted just because his willful endorsement of a product went hand in hand with a notification that the product is on sale.
The UI tries very hard to give the false impression that the Liker Likes the ad, not the brand actually Liked.
Yeah, I guess "Kevin likes Acme Inc's discount this week" is more accurate.
