Price alerts and watching a booking

Type your email in the price-drop box on the banner or on the web price checker, and Underbook checks the going rate for that stay once a day and emails you if it is at least 5% lower on two daily checks in a row.

• What you get: a confirmation, a note when a rate first appears if there was none yet, and at most one drop alert. The emails are about that stay only.
• No account: your email is stored with the stay you asked about and used only to email you about it (privacy policy).
• It stops after your check-out date, and one click on Unsubscribe in any of its emails stops it sooner (how to stop alerts).
• The extension keeps your email on your device, so next time one tap sets a watch; tap "not you? change email" to use another address.
• On the banner, the newest version (from 0.5.33) watches the price in the currency the banner showed; older versions watch it in US dollars.

When the alert comes, open the stay and check the room and the total before you book. More: hotel price drop alerts.

Yes: tick "I already booked this stay", enter the price you paid per night (all-in) and, if you know it, the last day of free cancellation, and Underbook checks once a day until then and emails you once if a listed rate is at least 5% lower on two daily checks in a row, so you can rebook.

• Where: on the web price checker for everyone, and on the extension's banner from version 0.5.29.
• The drop must also be at least 5 a night in dollars, euros or pounds, or a similar amount in your currency.
• Without a free-cancellation date it checks until check-in. The record is deleted automatically the day after check-out.
• It never needs your booking or confirmation number, your name or any payment details, so please do not type them in. Underbook does not see your booking and does not contact the hotel or the booking site: if you rebook, you book the new rate and cancel the old one yourself, after checking the room.

More: watch my booking.

Click Unsubscribe at the bottom of any Underbook email: one click stops that watch and deletes it, and no more email about that stay is sent.

• Your mail app's own Unsubscribe button, where it shows one for Underbook's emails, does the same.
• Each watch is separate: unsubscribing stops only the stay that email is about.
• Watches also end by themselves: a price-drop alert after your check-out date, a watch on a booked stay at your free-cancellation date, or at check-in if you gave none.
• Removing the extension does not stop a watch, because watches run on Underbook's service, not in your browser. Use the Unsubscribe link.
• No email to hand? Write to hi@underbook.co, or reply to any Underbook email, and we will stop the watch.
