After booking
Your rental car got cheaper. Now what?
Rental prices keep moving after you reserve, sometimes up, sometimes down. If you suddenly see a lower price for your dates, the good news is that a cancellable rate almost always lets you switch. The bad news is that plenty of people lose money doing it, either by cancelling too early or by ending up with a worse car.
If your rental car gets cheaper after booking, book the new offer first and cancel the old reservation only once the new confirmation has arrived. This depends on holding a cancellable rate. And on an offer that genuinely matches the old one on vehicle class, insurance, mileage and payment terms.

Why does a rental car get cheaper after booking?
Rental companies sell allocations, not fixed prices. When a vehicle class at a station books more slowly than planned, it gets offered cheaper so the cars are not left sitting on the lot. Cancellations by other customers push vehicles back into the pool as well. On top of that, brokers load the same supplier's rates at different times, which is why one car can cost two different amounts at two portals. An early-booking price is the price from back then. Not automatically the best one.
How big does the saving have to be?
Switching costs you a confirmed reservation, a bit of time, and with prepaid rates a few working days until the old money is back. Below ten euros the trade is rarely worth it. Where your own line sits depends mostly on the length of the rental: a daily rate three euros lower adds up to 42 euros over a fortnight, but to almost nothing over a long weekend. At RateRewind you set that threshold yourself, so only offers worth the effort reach you.
What is the safe order to switch in?
1. Book the new offer and commit to it. 2. Wait for the confirmation email and check the details in it. 3. Cancel the old booking. 4. Track the refund on the old payment. Cancel first and you can lose the cheaper car in the same minute. Nothing is held for you until a confirmation exists, and the strikingly cheap rates are often the last ones of their class.
How do you spot a genuinely comparable offer?
Four things decide it, and none of them shows up in the price: vehicle class, insurance cover including the excess, the mileage rule and the payment terms. Those are exactly what our algorithm checks before an offer counts as equivalent at all, and weaker insurance cover disqualifies it regardless of the saving. Apply the same standard when you compare by hand. Otherwise you save at booking and pay it back at the counter.
What if your booking is not cancellable?
Then the lower price is mostly just information. On a prepaid rate without a flex option the broker keeps part of the amount or all of it, and the fee usually swallows the saving. Do the arithmetic anyway: if your terms name a fixed cancellation fee rather than a total forfeit, and the new price sits well below it, switching can still work out. What applies is in your booking confirmation, not in the portal's general price list.
How often do you need to look?
There is no weekday and no time of day when rental cars reliably get cheaper. Finding something means running the same search with the same dates again and again, over weeks. That is exactly where most people stop. If you do it by hand, keep pickup and drop-off times identical: a return shifted by two hours can trigger an extra rental day and make the comparison worthless.
Does every rental car get cheaper after booking?
No. Prices can fall, rise, or not move at all before pickup. Whether there is anything in it for your booking depends on the station, the travel dates, the vehicle class and how full the fleet is, and none of those can be calculated in advance. So the honest expectation is not “I will save money” but “I will hear about it if something moves”. Your booking stands until you change it yourself.
Frequently asked questions
- Can I get the price adjusted after booking a rental car?
- Usually not. Unlike some hotel portals, rental brokers rarely operate a best-price guarantee that still applies once you have booked. The normal route is to book the cheaper offer again and cancel the old reservation afterwards.
- How close to pickup can the price still drop?
- Right up to the last day, because suppliers keep adjusting for occupancy. It only helps you while your cancellation window is still open, though. On many rates that window closes 24 to 48 hours before pickup, and after that a lower price is of no use to you.
- Do I lose my car if I book again?
- No, as long as you keep to this order. The new reservation is a separate transaction with its own booking number and does not depend on the old one. You only give up the old booking when you cancel it, and by then the new one is already in writing.
- What happens to extras like a child seat or additional driver?
- They belong to the booking you cancel and lapse with it. You select them again at the new provider, and it is worth counting them in straight away: a child seat is often charged per day and can eat a small saving entirely.
- Is switching worth it for ten euros?
- On a short rental probably not, on a long one yes. What matters is whether those ten euros still buy you the same vehicle class, the same insurance cover and the same mileage rule. If any of those is worse, it is not a better price but a different product.
