suspending Prime Seller fulfilled Programme.For buy shipping usage

Dear Sellers,

I hope this message finds you well. I am writing email to bring your attention in a prompt matter.

Actually, last week , we received a warning email from Amazon related to suspending Prime Seller fulfilled Programme.

I want to mention here that :

1- Initially, We were with Amazon buy shipping and when we faced lots of expenses so we shift to Royal Mail as our carrier.

2- We have been seeing "Buy shipping usage rate" was 0% at that time. We did'nt get any issue from at that time.

3-But last week, we received warning from Amazon.

Kind Regards,

Bahob
