> If the VPCs in the VPC peering connection are within the same region, the charges for transferring data within the VPC peering connection are the same as the charges for transferring data across Availability Zones. If the VPCs are in different regions, inter-region data transfer costs apply.
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.
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.
