Why is the fullfillment fee that AZInsight is showing different from the Amazon Revenue Calcualtor of an ASIN that I am currently selling?

If you're seeing a different Amazon fulfillment fee than what AZInsight is showing on an ASIN that you are currently a seller of please check the following:

Possible Cause
Check on Revenue Calculator
Check on AZInsight
Additional Notes
The amazon revenue calculator is using different package dimensions 
Verify the dimensions on the revenue calculator match what is on AZInsight. If the dimensions are different this may be due to an issue on Amazon's catalog where the API is not synced with what the catalog is showing.

For this to be fixed you need to submit an Amazon Seller Central case.

There are reported cases when the dimensions on the Amazon Revenue Calculator of an ASIN you are a seller of are different from what another seller is selling. This is a known issue with Amazon's Catalog not syncing properly. If you run into this case please change the dimensions on AZInsight to what you are receiving on your Amazon revenue calculator to make sure your Amazon Fulfillment fees are properly calculated.
