Show an estimated delivery date on the product page

A calculated delivery date, not a generic shipping-time range, sits next to the add-to-cart button so the shopper knows when the order will actually arrive before they commit.

What it is

The product page computes an estimated arrival date, for example "Arrives by Thursday, Aug 6", from the shopper's location or a default warehouse cutoff, and places it directly beside the buy box rather than inside a shipping policy page the shopper has to go find.

Why it works

A shopper deciding whether to buy is really deciding whether the item will be useful by a date they already have in mind: a birthday, a trip, a deadline. A generic "3 to 5 business days" range forces them to do that arithmetic themselves and guess whether weekends and processing time are included, and that gap in certainty is enough to send some shoppers to check a competitor's page instead of finishing the math. A computed date removes the guesswork at the exact moment the shopper is deciding, not after they have already added the item to the cart.

How to test it

Hypothesis
Showing a computed delivery date on the product page will lift add-to-cart rate, because shoppers with a real deadline in mind no longer have to estimate whether the order will arrive in time.
Primary metric
Add-to-cart rate (product page sessions)
Guardrail metric
Delivery-related support tickets, which could rise if the promised date is inaccurate and creates expectations fulfillment cannot meet
