Target B&M YMMV - 4moms rockaRoo Classic (grey) on clearance for $79.98.
Came across these at a clearance end cap in a local B&M - the 4moms rockaRoo Classic in grey for $79.98, down from $159.99. We have this and the mamaRoo and we really liked them both. Either way this is a great price for a brand new one. Below are both the direct Brickseek link and the Target link for product info.
