Im a bit confused - could you disambiguate here. I checked with a couple of people and they read the above to mean that any peering data transfer costs the SAME as if you were transferring data across availability zones. This is not free. Inter region transfer is a different tier

  Well sure, it's not free, but it's the same cost as if you were moving data within your AWS account, so they're not charging for the use of VPC peering specifically.
