# No shipping or fee disclosure — dev spec
Site: camphollow.com · Priority 8 · High · Effort: Medium (2-5 days)

## Problem
Shipping costs and delivery estimates are not shown until later, reducing cost transparency.

## Evidence (from the live site)
> The page's main headline reads “Your cart is empty”.
> A form on this page: its submit button is labelled “Add” and it carries 1 field.
> Page copy reads “Your Shopping Cart – Camp Hollow Skip to content Welcome to our new site, click here for the restock”.

## Current state
notes: No shipping or fee info on cart or product pages.

## Required change
notes: Display shipping thresholds and delivery estimates.

## Acceptance criteria
- GIVEN a first-time visitor on the affected page
- WHEN the change is live
- THEN Display shipping thresholds and delivery estimates.
- AND no layout regression at 375px / 768px / 1280px
- AND the changed control is keyboard-reachable with an accessible name

## Tracking
- Fire `cro_no_shipping_or_fee_disclosure` on interaction with the changed element
- Verify the event fires in BOTH variants before opening traffic

## Test plan
- Two-proportion z-test, 95% significance, 80% power
- 315,206 visitors per variant to detect a 5.0% relative lift
- Run at least one full business cycle; duration depends on traffic

## Rollback
Feature-flag the change; revert if the primary metric drops for 3 consecutive days.
