# Shipping delay warning — dev spec
Site: allbirds.com · Priority 3 · Urgent · Effort: Medium (2-5 days)

## Problem
The prominent 'orders may take up to 30 days to ship' notice at the top of the homepage creates immediate hesitation and may deter conversions by signaling fulfillment risk.

## Evidence (from the live site)
> Body sample: 'Due to increased demand, orders may take up to 30 days to ship.'

## Current state
h1: Wildly Comfortable. Super Natural.; cta: SHOP MEN / SHOP WOMEN; notes: The shipping delay notice is displayed prominently at the top of the page, above the hero messaging.

## Required change
h1: Wildly Comfortable. Super Natural.; cta: SHOP MEN / SHOP WOMEN; notes: Soften the messaging to 'Free shipping on orders over $100' and move the delay notice to a less prominent location, or replace with a trust-building line like 'Free 30-day returns' to reduce objection.
