Hello fellow sellers and Amazon support,

I’m reaching out to share a critical issue that’s severely impacting my business and to ask if anyone has experienced a similar situation.

Until May 1st, I was holding the Buy Box on approximately 1500–1600 listings consistently. My account health was excellent — my Order Defect Rate (ODR) was around 0.69%, well below the 1% threshold. There were no performance notifications, no account health flags, and no significant customer complaints or policy violations.

However, on or around May 1st, my Buy Box eligibility dropped suddenly to 0 across all my listings. Since then, I’ve not been able to win the Buy Box on any product, even though I am currently the lowest-priced seller on hundreds of listings.

To clarify:

My account has never been suspended or warned.

My metrics remain within Amazon’s required thresholds.

I’ve contacted Seller Support, but the only explanation I received was that the issue might be related to my ODR, which clearly was not a problem when the loss occurred.

This abrupt change with no clear reason is not only frustrating but devastating for my business, as Buy Box visibility directly affects our sales.

I’m hoping someone from the community or Amazon's support can shed some light on:

Whether there might be a system bug or recent algorithm change affecting Buy Box allocation?

What additional steps I can take to recover my Buy Box eligibility?

Any help or shared experience would be greatly appreciated.

Best regards,
