Updated July 2026. Store-level figures cover 3,781 stores with at least 20 restock orders, July 2025 – June 2026, in USD.

Sending timely notifications about product availability can significantly boost sales. But the data continues to show that notifications lead to even more impactful outcomes: customers don’t just purchase the item they were notified about — they frequently add more to their cart.

A Closer Look at Customer Behavior: More Than Just the Notified Product

Stores by how much extra customers spend beyond the notified products, among stores with ≥20 restock orders in the year.

Across 3,781 stores, 95% see customers purchase more than just the notified product — up from 90% when we first published this analysis. Only 5% of stores see shoppers stick strictly to the item they waited for.

This underscores a critical point: notifications do more than bring customers back to complete an intended purchase — they open a high-intent shopping session with room for upselling and cross-selling.

How Much More Are Customers Spending?

Insights

• The median store sees total purchases 37% larger than the value of the notified products themselves.
• For 56% of stores, customers spend 0–50% more than the notified item; for another 24%, they spend 50–100% more.
• At the top, nearly 16% of stores see customers spending at least double the notified product’s value, and 4% see them spend triple or more.
• Platform-wide, 36% of all restock-order value comes from extra items: the median restock order is $87 against a median alerted-item price of $52.

What this means. When customers come back after a notification, they arrive ready to shop, not just to check out. Make sure the page your alert links to carries recommendations, bundles, and cross-sells. More than a third of the session’s revenue is decided after the click.

The bottom line. Notifications don’t just recover lost sales — they grow them. With 95% of stores seeing customers buy beyond the notified product and the median store gaining 37% in extra basket value, the restock alert has quietly become one of the highest-intent sessions in eCommerce. Treat it like one.
