Dad and I bought 3 bottles from the KC store last night. I have nearly a full bottle already so I figured I only needed one more for this season (dad took the other 2). It's funny cause they didn't even have it marked down in the store and I thought there was a mistake with the ad. I took a bottle to the scanner and sure enough, $19.99. It's almost like they want to keep the sale a secret so they don't sell out too quickly.
