Free shipping bar

A progress bar with a truck toward the free-delivery line.

A bar that fills toward the total that earns free delivery, with a small truck riding its tip and the amount that is missing in words. The total is a prop and a slider lets a visitor try others. No countdown, no urgency tricks, no cart and nothing sent anywhere.

Build one with your agent

Paste this into your agent. It asks you before it signs in, pays or goes further than checking and publishing.

Build me a Taggor component like "Free shipping bar" (free-shipping-bar): A progress bar with a truck toward the free-delivery line. Fetch https://taggor.dev/agent-setup/prompt.md and follow its instructions to set me up for Taggor. Ask me before you sign in, create an account, accept terms, pay for anything or type a secret. Check it with `taggor check` and publish it with `taggor publish`, and stop there. Do not promote it to production, attach it to a site, roll back anything or use --yes, --force or --force-drop-invalid unless I ask for exactly that in this conversation.
