Amazon is facing a US class-action lawsuit alleging it charged higher prices linked to Trump-era tariffs but failed to refund consumers after these were overturned. The suit claims it earned hundreds of millions of dollars from affected products and was unjustly enriched. The plaintiffs cite a SCOTUS ruling in February 2026 finding certain tariffs imposed under the IEEPA unlawful. The case could affect pricing transparency and refund obligations across US ecommerce.
