“How will I hear about a change?”

A changed test cart’s page shows:

• The expected and the new price X-ray, one above the other; a discount that’s new is drawn in blue.
• What changed: each discount, the shipping rate, and the total, expected against now.
• Likely causes: the store changes made just before, ranked, each with what changed (“$10 off $80 was edited”).
• What moved: one sentence per change (“Customers now pay $530.00 instead of $540.00.”).
• What to do: Accept new result if the new price is right, or undo the change in Shopify, with buttons to open the discounts that changed.

After each round of checks, one email with every change not sent yet and every test cart that couldn’t be checked. Its subject says the cart and the prices: “Price changed: Hydrogen with HYDRO10 now $530.00 (was $540.00)”. It shows the price X-ray, expected beside now, and the most likely cause.

• A change is emailed once. If its price moves again with nothing new in your store, it’s emailed again only after 24 hours.
• In Settings → Alerts: Email alerts, Email when a test cart can’t be checked, and Send alerts to (otherwise your store’s email).
• Turning emails back on starts from then: changes found while they were off aren’t sent as a backlog.

1. In your Slack workspace, create an incoming webhook for the channel the alerts should go to.
2. In Settings → Slack, paste its address (it starts with https://hooks.slack.com/services/) and turn on Slack alerts.
3. Send test message to check it arrives. Remove disconnects it.

The address is stored encrypted and never shown again in full.

• Mute 7 days on a test cart: no scheduled checks and no alerts until then. Unmute ends it.
• On Free there are no emails: changes show on Home, in Test carts and on the change page.
