I believe they had been, and perhaps still are, charging per-shipment fees to "high-volume" shippers. And that is good in that it is leveling the charge on the culprit (the ones benefiting from e-commerce the most). Retail shippers already pay more and that wouldn't hit the source of the problem. And most shippers have contracts that may prevent sudden price increases based on volume (typically volume is rewarded).
