Other Car Rental Programs/Partners (ie. Alamo, Enterprise, Sixt) - Nice offers for car hire by Europcar

Hi everyone,

I've found some nice offers for car hire by Europcar:

-15% = http://www.europcar.com/EBE/module/booking/FirstStep.do?promoCode=44091496 (formally the offer was expired but mysteriously it still work)

-10% + free upgrade = http://www.europcar.com/EBE/module/booking/FirstStep.do?promoCode=44035484

Did anybody use these discounts? Do they work?
