Is the budget code a 'think of trust'? Or simply none really work... or perhaps I have a completely incompatible reservation.

Just want a 1-day one-way rental in SoCal (Pasadena to LAX).

Not a single code I have tried has resulted in any lower rate than had I not put a code at all. Does the site never show the savings until you actually show up at the office to rent the vehicle? (i.e. 'wow, I hope I entered a valid code'), or... have I been entering invalid/incompatible codes to what I want to do, and instead of the site showing me an error, it's simply accepting the code, but, leaving the price (rightfully I guess) unchanged.

If it's the case of the later, anyone have a nice code for a simple 1-day and one-way rental?
