A feces-encrusted swim diaper tanked a family business after Amazon re-sold it as new, Bloomberg reported, triggering a bad review that quickly turned a million-dollar mom-and-pop shop into a $600,000 pile of debt.

Paul and Rachelle Baron, owners of Beau & Belle Littles, told Bloomberg that Amazon is supposed to inspect returned items before reselling them. But the company failed to detect the poop stains before reselling a damaged item that triggered a one-star review in 2020 that the couple says doomed their business after more than 100 buyers flagged it as "helpful."

"The diaper arrived used and was covered in poop stains," the review said, urging readers to "see pics."

A court has dismissed a proposed class-action lawsuit alleging that Amazon's Buy Box was rigged to rip off customers seeking the best deals on the platform.

The suit followed 2022 antitrust probes in the European Union and United Kingdom that found that Amazon's Buy Box hid cheaper items with faster delivery times to preference Fulfilled By Amazon (FBA) sellers since at least 2016.

As a result, Amazon had to change its Buy Box practices and earn back the trust of customers and sellers, the company said in a 2022 blog. Among changes, Amazon agreed to treat all sellers equally when featuring offers in the Buy Box and to promote a second competing offer when a comparable deal is available at either a lower price or with a faster delivery time.
