This is for anyone, like me, who didn't know you could buy this. It's insurance cover that covers you for your excess charges if you are unfortunate enough to have a prang while driving abroad.
Below is an example of the savings you can make.
I was looking for car hire for a week in Ibiza (29 Oct - 5 Nov). I found an Alfa Romeo Giulietta for £39.45.
Collision Damage Waiver (CDW)
Theft Protection (TP)
PLS (Premium Location Surcharge)
Third Party Cover
It did NOT include 'Excess Refund Protection' which covers you for your excess. This 'Gold' option increased the cost to £75.23
To upgrade to the all-singing and dancing 'Platinum' insurance, which further includes 'Driver's Choice - will Reimburse Fees for: Towing, Lock-Out & Damage caused to: the windows / windscreen / glass - interior - wheels and/or tyres - the roof', the cost rises again to £96.23.
This means an increase of about £52 above the cost of the basic 'inclusive' insurance.
Now the good bit :)
I got a quote from https://www.carhireexcess.com
for Car Hire Insurance Excess cover, and to buy the equivalent cover to the 'Platinum' cover cost a measly £12.53 all-in, which includes everything that the £52 to the car hire company includes.
Thus the £96.23 total cost of the fully covered car hire now becomes £51.98.
Good, eh? :)
