What this question tests

Tests product design for a new delivery tier that trades speed for cost savings, requiring a clear incentive structure for both sides.

Clarify the goal: a no-rush option should let price-sensitive customers save money or gain other value by accepting a longer delivery window.
Segment on price-sensitive customers ordering non-urgent items, like a routine grocery restock, versus those ordering something needed immediately.
Identify the mechanism: batch no-rush orders together with nearby deliveries during the same time window to improve delivery efficiency and offer a discount funded by that savings.
Design the flow: an opt-in flexible-window checkout option offering a delivery discount or loyalty points in exchange for a 2 to 4 hour delivery window instead of instant.
Define success as opt-in rate for the no-rush option, cost savings per batched delivery, and no drop in customer satisfaction for orders using this tier.

Names the real underlying mechanism, delivery batching efficiency, that makes a discount economically sustainable rather than just offering one arbitrarily.
Explicitly separates urgent and non-urgent order intent as the basis for segmenting who this option should target.
Ties the incentive, discount or points, directly to the cost savings the batching actually creates.

Offering a discount for no-rush delivery without any real operational efficiency gain funding it.
Not addressing which customer segment or order type this feature is actually meant for.

How would you set the discount so it's attractive without eroding margin?
How would you handle a no-rush order that ends up delayed beyond the promised window?
