Initial Amazon Prime Day order size, spend slip from 2024

Amazon kicked off its 2025 Prime Day sales extravaganza with some slightly disappointing numbers.

Data from the Numerator Amazon Prime Day Tracker shows that as of 4 p.m. ET on Tuesday, July 8 (day one of Prime Day 2025), the average order size was $58.37, down approximately 1.7% from $59.78 in the same reporting period during Prime Day 2024.

Numerator data also indicates that 42% of households shopping Prime Day have already placed two or more separate orders (slightly less than the 45% of households that had placed two or more separate orders during the same time period in 2024), bringing the average household spend to roughly $106.41, down 3.6% from $110.4 the prior year.

The top items as of 4 p.m. ET on the first day of Prime Day 2025 were liquid IV packets, Dawn Platinum powerwash and premier protein shakes. Two-thirds of Prime Day items (66%) have sold for under $20, while 3% are over $100 — the average spend per item is $25.46, roughly 9% less than $27.97 at the same point during Prime Day 2024.

The top categories buyers say they’ve purchased are apparel & shoes, health and wellness, household essentials and home goods like bedding & décor. Fifty-six percent of shoppers purchased something they had been waiting to buy until it went on sale.
