Got this link in my email today.

Please Touch Museum for half price! Awesome deal, especially since it includes the carousel, and if you take a kid on, you only have to use one ticket, not two. So I bought the 4 deal today which includes 4 carousel tix, meaning my kids each get to ride twice.

They ran this deal over the summer and I just used my tickets from that yesterday. I was considering getting a membership, but if they keep running this deal, no need for that.
