In a blog post, Amazon rejected a Wall Street Journal analysis that linked recent price increases on everyday items to U.S. tariff policies. The WSJ study reviewed 2,500 products, finding an average 5% rise between January 20 and July 1.

Amazon said the methodology was flawed, accusing the paper of “cherry-picking” examples and overlooking that some items were temporarily discounted during the initial data collection. The company pointed to specific cases where price changes reflected the end of sales promotions.

The e-commerce giant also underscored the volatility of its pricing, warning that snapshot comparisons may not capture the full picture.

Meanwhile, U.S. inflation data shows prices have inched higher more broadly, with June figures showing a 0.3% monthly and 2.7% yearly increase in consumer prices.
