Yeah, there's a Lannan Bobble head and an Uncle Slam bobble this year. Not sure if its Aug 22 or 23. Have to check!
Got Justin Maxwell last year!
I think they are promoting Freebie Fridays, so its probably on a Friday.
It looks like they probably made a mistake on the website. You are right, as part of the freebie friday promotion it should instead be on August the 21st rather than Saturday the 22nd.
