Question that may seem strange to you.

As a matter of fact, up to last week, I used to book my avis car on the us site , which was far better for rates than the french one .


And then, I was told by friends, and the information was available in papers too (Le Point, in France), that the spanish site avis.es was far better.
I had a look, and saved 20 per cent, WHAT EVER the rate codes (AWD) are.

And, it is the same for Hertz, where the german site seems to be better (wahtever the cdp is).

Does it work for you too generally ?

is there a better site than these ones that some of you use to save more ?
Whay are there so many differences (rate codes, coupons, country web sites ...) ?
