The Editorial Team has been busy in the days since our friend @GGX opened this thread:
The years-extant SHC page “Bank account and credit card information for your seller account” @ https: //sellercentral.amazon.com/help/hub/reference/19791 has been retitled “Bank account and credit or debit card information for your seller account.”
The equally-vintaged page “How to update my credit card information?” @ https: //sellercentral.amazon.com/help/hub/reference/202131360 has been retitled “Update credit or debit card information.”
There’s also a new page I hadn’t seen before, titled “Add, delete, and verify your credit or debit card information” @ https: //sellercentral.amazon.com/help/hub/reference/UQLF3C3HXXXERLC.
I leave it to the gentle reader to decide what might be Amazon’s motivation for making these changes…
