Combine free shipping progress with a delivery promise.
"Add $12 more for free shipping by Tuesday!" hits two conversion levers at once — average order value (free shipping is the most effective AOV booster) and urgency (a specific Tuesday is more concrete than "soon"). ShipCast pairs them in one cart-page nudge.
The problem
Most stores show "Add $X for free shipping" as a separate banner. Most stores show "Estimated delivery" as a separate widget. Customers process them separately. Combining the two — "Add $X more for free shipping BY Tuesday" — turns a logistical hint into a buying reason.
How it works
Step by step.
No code, no developer required. Drop the ShipCast block into your theme and the feature lights up.
Cart page in progress state alongside the qualified state.
- 01
Set your free-shipping threshold ($50 by default).
- 02
Customize two templates: in-progress and qualified.
- 03
ShipCast renders the right pill on the cart page. Cart below threshold → blue pill: "Add $20.00 more for free shipping by Tuesday!"
- 04
Cart at or above threshold → green pill with ✓: "You qualify for free shipping by Tuesday!"
What's included
Everything that ships with this feature.
Multi-currency aware
Amount formatted in the shopper's cart currency via Intl.NumberFormat.
Two states
In-progress and qualified — different colors, different copy.
Configurable threshold
Default $50, edit in the dashboard.
Editable templates
Supports {amount} and {date} placeholders.
Cart-only by design
Doesn't render on PDP — see callout below.
Layers with the widget
Renders below the cart's delivery estimate, not in conflict with it.
Cart-page-only by design
ShipCast intentionally doesn't render the threshold on product pages. A "you need $X more" message there is misleading because the customer hasn't built a cart yet. Cart-page rendering keeps the messaging accurate.
Who needs this
Is this for you?
Stores running free shipping over a threshold (most stores). Brands focused on AOV growth. Stores where delivery date plays into the purchase decision (gifts, perishables, events).

ProShow customers their return deadline automatically
"What's your return policy?" is one of the top three pre-purchase questions. "When does my return window close?" is one of the top three post-purchase tickets. A concrete date — "Easy returns until April 5" — on every order confirmation eliminates both.
