What people get wrong about deposits
- It must be a credit card in the main driver's name - 1% of cars here take a debit card for it.
- Full cover bought when you book does not remove it: the desk still holds the deposit (DiscoverCars' own terms).
- A separate excess policy does not lower it either - it pays you back after a claim.
- It is released after you return the car, usually within days to a few weeks, depending on your bank.
