Did you map your child listing to the parent listing in PriceLabs? You'll want to do that for billing, especially. Then there is a setting that says to copy everything from the parent to the child. (Aside: You can make adjustments on the child or parent as a pricing offset if you like as well.) PriceLabs should have some good help articles as well once you are in your account. Love having my prices syncing and dynamic with PriceLab's service!
