Not the same thing, but bought some groceries last week. While leaving the store walked by the flowers and decided to buy a bunch marked $19.95, but pretty nice size. Went back in to the auto checkout and it rang up $23.99. Decided, screw this, and went and got a smaller bunch marked $13.95. You guessed it, it rang up for $15.95. This time, talked to the manager who quickly plugged in her card and gave them to me for the $13.95, saying it must be a "recent price change."
