Budget - Adding Coupon to Existing Reservation?

I've already tried searching for the answer to this, so I apologize if this question has already been asked/answered....

I have an existing reservation in Orlando/MCO that's using BCD code X474200. Without changing the rate I've already "locked-in" with this BCD, can I modify the reservation and add a coupon??

I know that you can go to budget.com and change a reservation, but I'm not sure if it allows to you add a coupon...and I don't want to risk losing my rate until I know I can do it.

Thanks.

you can always change the bcd or coupon on an existing reservation, but you may not like the results...just don't book the change if you don't like the results

Indeed; you won't be committing to the change until you see the option to "accept changes." If the price isn't to your liking, simply click "reject changes."
