US online sales during Amazon.com's Prime Day shopping event rose 6.1% to $12.7 billion (€11.3 billion) from last year, as inflation-hit Americans hunted for discounts on the e-commerce platform, Adobe Analytics data on Thursday showed.
Shoppers spent $6.3 billion (€5.6 billion) on the second day of the big sale as deep discounts on products such as toys and appliances drew in customers who have otherwise cut their non-essential purchases due to rising prices.
Amazon said over the two-day event, Prime members bought more than 375 million items worldwide and saved more than $2.5 billion (€2.2 billion) on several deals, making it the biggest Prime Day event ever.
The second day saw an increase in sale of back-to-school items including stationary and office supplies, said Vivek Pandya, lead analyst at Adobe Digital Insights.
"The numbers came in the range that we anticipated," he said.
Online sales on July 12 for appliances were up 52% compared to average daily sales in June, while apparel was up 24% and stationary and office supplies was up 76%.
Average order size rose to $54.05 from $52.26 last year during the two-day event, according to data firm Numerator.
Adobe data on Wednesday had showed that US online sales during the first day jumped nearly 6% to $6.4 billion (€5.7 billion) from a year ago.
On the second day, consumers were most enticed by 14% discount for electronics and 12% for apparel and toys, Adobe said.
"Last year we saw discounts in the mid single digits... (this year) we have them in the higher single digits, almost a bit into the double digits," Pandya said.
Amazon has also offered for the first time Prime Day travel discount, partnering with travel booking site Priceline, while its loyalty program members were also given access to "invite-only deals" in the weeks leading up to Prime Day.
Separately, about 900 Amazon workers at a warehouse in Coventry, in Britain are striking for three days during the Prime Day shopping event over a pay dispute, which Amazon said will not cause any disruptions for customers.
Adobe's data relies on direct consumer transactions based on over 1 trillion visits to US retail websites.
