Study: Amazon’s Prime Day 2019 was big – but how big?

A new study reveals whether Prime Day 2019 sales reached expected highs.

According to “Amazon Prime Day 2019: Pricing Insights,” an analysis of the most recent Prime Day’s performance from Coresight Research and competitive intelligence provider DataWeave, Prime Day 2019 generated global sales in the region of $5.3 billion this year, up by slightly more than one-third from Coresight’s estimate of $3.9 billion in sales for Prime Day 2018.

Amazon under-shot Coresight’s pre-Prime Day estimate that it would generate global sales of around $5.8 billion on Prime Day 2019, up by around one-half year-over-year. Amazon does not disclose figures for sales generated during Prime Day, but Coresight bases estimates on information disclosed by Amazon following Prime Day, and excludes revenue from new Amazon Prime signups.

In addition, using a proprietary data set on prices in the categories of electronics, health and beauty care (HBC), men’s fashion, and women’s fashion on Amazon’s US site, Coresight analyzed the level and distribution of discounts on Amazon during July 15 and 16, compared to product prices on July 8.

On the first day, 23.6% of electronics products were offered at lower prices, but 13.2% were offered at higher prices than on July 8.

On day two, 28.3% of products were offered at lower prices but 14.2% were offered at higher prices than on July 8. The average discount was 5.1%, with a range from 0.01% to 19.6%. Between July 15 and 16, only 3.8% of products had a price difference that was greater than one dollar.
