No, that is not a typo. Yes, you can get any one of the Mixis dolls for only $19.95 - postage NOT included. The ad states that that is 70% off the regular cost. If you can get any of the First Edition dolls, that means you get very cool boots or leather-like loafers or suede boots. You can see photos of the Mixis dolls here under this link.
The only "catch" is that you have to like the Mixis dolls on Facebook first. Small price for a great deal if you are already on Facebook.
