Hello Amazon Team!

We are having an issue with Amazon Buy Shipping not showing the proper rate for Fedex Standard Overnight (shipping with Fedex Envelope). We have correctly linked our Fedex account with negotiated rates. We are also using the correct dimensions for Fedex Envelope: 9.5 x 12.5 x .5 in. When we ship on Shipstation (or other platforms) we are able to get a rate over 20% cheaper when selecting our Fedex Account rates vs what we see in Amazon Buy Shipping on the Amazon website (or shipstation/veeqo using Amazon Buy Shipping).

This is a substantial amount of additional cost on high volume and we'd really like to get some help sorting this out to get the proper rate to load for us on Amazon Buy Shipping. It appears that no matter what dimensions we input for Fedex Overnight, it always produces the same rate as if we were shipping "package", not Fedex Envelope.

The 2 Day Fedex rates work fine for us and the rate matches what we spend outside of Buy Shipping as long as we use the proper dimensions (thanks to the tips for package dimensions 9.5 x 12.5 x .5 in. as outlined in the article titled FedEx shipping services and restrictions).

We've tried opening a support case 16974601841, but there was not a resolution.

I'm also seeing the same exact issue I've seen some others have when searching the forum.
