Candy Store Mistake

The first sentence is passive. Okay, let that slide. The comma after looking is unnecessary. Okay, let that slide. It's should be written its unless the author of this sign meant, "Each box has it is own unique surprise mix." I found this one in Bethany, Missouri. This store had some great deals on candy, but no toilet paper in 2 out of 3 stalls. (That is another post on another blog.)
