Reading these comments make me realize how lucky I am to live in Canada!
Depends on the state you live in, where you go and what kind of ultrasound you get.. I live in iowa but travel to illinois for my 3d/4d ultrasounds.. the package I get is about 200$ and worth every penny!
Out of pocket mine cost $450, but it was done for diagnostic reasons, it wasn't one of those places where you go mostly just to see your baby.
The gender one cost me $53. The regular ultrasound to check the babies health is a little more expensive.
