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 U.S. online sales during the first day jumped nearly 6% to $6.4 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.

Rival retailers including Walmart, Best Buy, and Target are also providing greater discounts.

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 U.S. retail websites.
