We never used the toll thing. We just used cash. It was no different to the cash booths I've used in Sydney, (lady in there waiting to take your money). The car seats we got from Super Target in LA. We caught a taxi to the mall and we ended up bringing them home. We needed a booster and a car seat and they were under $40 each. I was very happy especially since V Australia let me use it on the plane. So much easier for P to sleep.
