I have a minivan rented from National for 9/17-9/24. We used the product code of WWEB, entertainment coupon and contract id for $257.60. The priceless code gave me the same price as the entertainment contract id. But, I keep seeing threads from some of you how every day you are getting cheaper rates. But everytime I check, I get the same price. Is it due to the product code? Unfortunately, when I don't use the product code its upwards of $400 for the minivan so I need it at this point. Thanks. Just curious how the rates are changing for some of you and what you are using.
