I made a Budget reservation weeks ago using Entertainment book code
X443034, received a very good rate for the week at IAD on a compact class...used the entertainment book coupon MUGZ683 for an additional $20 discount. Today I received an email from Costco showing a coupon code of MUGZ127 good for $25 off the weekly rate.

Does anyone know if I have to use the Costco BCD# to take advantage of this bigger weekly savings, or can it be applied to the existing quote using the entertainment BCD#? Do I just give the rental counter the new coupon code when beginning the rental? When I try to get a new quote now, the rate is much higher, as I am only 6 days away from the rental.

It is only $5, but that will buy me some gas. uhhh perhaps 1 gallon? LOL Thanks for comments.
