D005927 is no longer working for UK rentals. I've used this code for several years, but today, I get all through the reservation (no pop ups or anything to say its invalid) and it simply fails to complete (see my post on is the avis website broken). Through a process of elimination, I've discovered the code is the problem.

Incidentally, I have used this code many times in the UK and never been asked for verification, so if it works for you, go for it.

Edited to add: I seem to be having the same problem with every code - bah humbug. Yet, I can make a non-discounted booking with no problems. I'll try again tomorrow
