How Rentalcars bookings actually work
Rentalcars is a broker rather than a rental company, so the counter you collect from sets its own deposit, fuel policy and insurance upsell. Those terms cost more than any code returns.
A broker books it; the local counter sets the terms that cost you. The promo code field is applied during the booking flow before payment. Counter charges such as deposits, fuel and young-driver fees sit outside the discount.
- 1
Read the counter terms, not just the price
Deposit size, fuel policy and insurance upsell are set by the local supplier and cost more than the discount.
- 2
Check the fuel policy
Full-to-full is usually cheapest; prepaid fuel is priced above pump rates unless the tank returns near empty.
- 3
Decide on excess cover in advance
Counter-sold excess waivers are expensive, and arranging cover separately usually costs far less.
- 4
Check the driver age and licence requirements
Young-driver surcharges and licence rules are applied at the counter regardless of the code.
