A price watcher for after you have booked
Most sites help before you pay. RateRewind starts afterwards: you already have a cancellable rental. We keep checking whether a genuinely comparable offer gets cheaper.
RateRewind is a price watcher for rental cars you have already booked: you save your cancellable reservation, we keep checking several sources, and we only get in touch when an offer is cheaper with a comparable vehicle class, insurance, mileage allowance and payment method.

Not another car-rental comparison site
A car rental comparison site searches for a new trip. RateRewind starts after you book: we know the location, dates, vehicle class, insurance, mileage and payment terms of your reservation, and look specifically for cheaper offers that match.
Not a classic price alert either
Metasearch price alerts tell you Palma got cheaper *before* you book. Useful, but they do not watch the reservation you already hold. This watcher monitors the booking you have.
What we do
Add your booking through the form or forward the confirmation to your personal RateRewind address. We then check several sources regularly. You only receive a price alert when a cheaper offer also matches your vehicle class, insurance, mileage and payment terms. The decision to switch remains yours.
What we do not do
We do not rebook automatically or guarantee savings. An offer with worse insurance is not presented as a cheaper alternative and never triggers a price alert.
Free plan and how we get paid
The Free plan costs nothing and needs no card. If you rebook cheaper through a disclosed offer link, we may earn a commission. That does not change your price.
Who this is for
Best for cancellable rentals with pickup still in the future. Not for locked prepaid rates, and not for people who are still shopping for their first booking.
Frequently asked questions
- What does a rental car price watcher do?
- It tracks the price for a booking you have already made. Instead of repeating the same search yourself every few days, you save the reservation once and get notified when a comparable offer is cheaper.
- How is this different from a price alert before booking?
- A classic price alert watches a search query before you book. A price watcher tracks your actual reservation afterwards, using your station, your dates and your terms as the benchmark for comparability.
- Which bookings can I track?
- Cancellable rental car bookings with a pickup date in the future. On non-cancellable prepaid rates tracking achieves nothing, because a lower price can no longer be used.
- What does it cost?
- The free plan costs nothing and needs no credit card. If you actually rebook cheaper through a marked offer link, we may earn a commission. Your price does not change because of it.
