Amazon Prime Big Deal Days Nears $10B in US Online Spend

What happened

US shoppers spent close to $10 billion online during Amazon's Prime Big Deal Days, the two-day October sales event that has become a key precursor to the holiday shopping season, according to Retail Dive. The event also lifted sales at competing retailers, including Walmart, as consumers used the period to compare prices and secure early discounts.

The spike in spend reflects a now-familiar pattern: Amazon's promotional calendar increasingly sets the tempo for the wider retail sector, with rival chains timing their own offers to coincide with — or counter — the e-commerce giant's deal windows.

Why it matters

For experience and commercial leaders, the event is a live case study in how retailers condition shopping behaviour well ahead of peak season. Consumers are increasingly trained to delay purchases and wait for scheduled discount windows, which reshapes demand curves, inventory planning and customer acquisition costs across the industry — not just for Amazon.

The spillover into competitors' sales also signals that shoppers are treating these events as a broader "deal season" trigger rather than a single-retailer promotion, prompting multi-brand price comparison and loyalty switching at scale.

By the numbers

• Nearly $10 billion in US online spend was recorded during Amazon's two-day Prime Big Deal Days event.
• Two days was the duration of the promotional window driving the spend surge.

The Renascence take

The headline number is less interesting than what it reveals about how deeply anchored consumer expectations have become around scheduled discount events.

Every major retailer now effectively operates on Amazon's promotional calendar, whether they intend to or not — shoppers have been trained to wait, compare and switch the moment a deal window opens. The real competitive question isn't who discounts hardest during these two days, but who earns loyalty in the other 363, through service, reliability and experience that doesn't depend on a markdown. Retailers chasing the spend spike without investing in year-round trust are simply renting attention Amazon already owns.
