Amazon Prime Day — one of the biggest online shopping events of the year — has come and gone, moving to October this year from July. This event, originally 24 hours long, has now expanded to a 48 hour savings extravaganza. As last year’s Edison Trends report about Prime Day 2019 sales had shown, the event has consistently led to record-breaking sales, and this year was no different.

In such a turbulent year for everyone due to COVID-19, all eyes were on Amazon Prime Day and the competing sales as an indicator for the ecommerce industry at large. To find out how the events performed, Edison Trends analyzed over 370,000 US transactions before, during, and after Prime Day 2020.

How did 2020 pre-Prime Day sales compare to those from previous years?

Figure 1: Chart shows spend at Amazon in the week before Prime Day, comparing 2020 vs. 2019 vs. 2018. Note: The highest spend per day has been set to 100, and all other values scaled accordingly. This analysis is based on over 600,000 transactions. See below for dates analyzed.

With mounting competition from competitors, Amazon Prime Day started a limited number of sales early this year. Pre-Prime Day spending has increased each year. Looking at the total amount customers spent at Amazon in the Monday through Sunday before the event, 2019 saw a 22% jump over 2018, while 2020 was a whopping 65% over 2019. All three years, however, followed Amazon's typical pattern, with spending at a high point on Monday and a low on Saturday.

How did the first 7 hours of Amazon Prime Day 2020 sales compare to previous years?

Figure 2: Chart shows estimated spend during the first seven hours of Amazon Prime Day by hour, comparing 2020 vs. 2019 vs. 2018, according to Edison Trends. Note: Data have been scaled so that the highest hourly spend is set to 100. This analysis is based on over 45,000 transactions. The time periods represented are: July 16, 2018 at 3pm ET through July 16, 2018 at 10pm ET, July 15, 2019 at 3am ET through July 15, 2019 at 10am ET, & October 13, 2020 at 3am ET through October 13, 2020 at 10am ET.

In each of the past two years, Amazon has started its Prime Day sale at 3am ET. In 2018, they had started at 3pm ET. 2018's customer spending in the first seven hours in the sale was higher overall than in the following two years, but 2020 still beat 2019. During the 3am ET hour, at kickoff, customers spent 46% more than they had in the kickoff hour in 2019. In each hour, customers continued to spend more than they had a year ago, but out of these seven hours, the 3am slot has shown the largest YOY increase. (The average YOY increase among the hour slots was 26%.) In both 2019 and 2020, spending dropped going into the 5am hour and then grew as the morning progressed.

How did all 48 hours of Amazon Prime Day 2020 sales compare to previous years?

Figure 3a: Chart shows estimated total spend by day and hour, during all 48 hours of Amazon Prime Day, comparing 2020 vs. 2019 vs. 2018, according to Edison Trends. Note: Data have been scaled so that the highest hourly spend is set to 100. This analysis is based on over 370,000 transactions. The time periods represented are: July 16, 2018 at 3pm ET through July 18, 2018 at 3pm ET, July 15, 2019 at 3am ET through July 17, 2019 at 3am ET, & October 13, 2020 at 3am ET through October 15, 2020 at 3am ET.

The chart shows customer spending for all 48 hours of Prime Day over the last 3 years. 2020 has beaten 2019 in every hour except Day 1 at 1pm. The hour of 9pm on Day 2 surpassed its 2019 counterpart the most, with spend increasing 64% since last year. The top hour for spend for Prime Day 2020 was Day 1 at 11am ET. For 2019, it was Day 1 at 1pm ET.

The average increase over 2019 across all 48 hours was 38%. Looking at just the first 24 hours, the average hourly increase was 31%; for the next 24, the figure was 46%.

Figure 3b: Chart shows estimated total spend, during all 48 hours of Amazon Prime Day, comparing 2020 vs. 2019 vs. 2018, according to Edison Trends. Note: Data have been scaled so that the highest hourly spend is set to 100. This analysis is based on over 370,000 transactions. The time periods represented are: July 16, 2018 at 3pm ET through July 18, 2018 at 3pm ET, July 15, 2019 at 3am ET through July 17, 2019 at 3am ET, & October 13, 2020 at 3am ET through October 15, 2020 at 3am ET.

Prime Day has grown each year. In 2020, customers spent 93% more across all 48 hours than 2018, and 36% more in 2020 than 2019. Put another way, 2019 spend was only about 75% of what it has been in 2020.

Looking at the first 24 hours by themselves, total spend was up 30% over the first 24 hours of 2019. For the second 24 hours, that figure was 44%.

How much market share did competitor sales earn during Amazon Prime Day in 2020 compared to 2019?

Figure 4: Charts show estimated market share of spend, during all 48 hours of Amazon Prime Day, comparing 2020 vs. 2019, according to Edison Trends. Due to rounding, numbers may not add up to 100%. This analysis is based on over 370,000 transactions. The time periods represented are: July 16, 2018 at 3pm ET through July 18, 2018 at 3pm ET, July 15, 2019 at 3am ET through July 17, 2019 at 3am ET, & October 13, 2020 at 3am ET through October 15, 2020 at 3am ET.

Walmart’s Big Save event ran October 11 - 15, while Target’s Deal Days ran on the 13th and 14th. In 2019, Amazon took 93% of the spending pie between these four merchants over all 48 hours of Prime Day. This year, the figure was similar, at 91%. Likewise, figures for Walmart, Best Buy, and Target remain within 1% of where they stood in 2019, with Walmart and Best Buy in second and third and Target in fourth.
