Check 7 / 18 LOW impact In the full checklist
Estimated delivery date in cart + checkout
What this check is
The delivery estimate carried from the product page into the cart and checkout is what stops the shopper reopening a second tab to check the shipping policy at the last moment.
How to implement it
Render the same calculated date range in the cart summary and on the checkout shipping step, driven by the delivery estimate logic rather than typed per product. Update it when the destination changes.
How to verify it
Add an item to the cart, change the destination country and confirm the date range updates in both the cart and the checkout shipping step.
