I believe this has been mentioned previously, but Jet West is an airline in Canada that has a BCD code for Budget that chops about $50 off my weekly rental rate. This has been the only code that has cut down my rate.

BCD A376100

Jet West does not have a frequent flyer program or any other club inwhich you can become a member. So, it seems pretty safe to say that anyone can use this code.

It also seems to work along with most of the coupon codes that have been mentioned!

Good luck!!!
