If it makes you feel better, I just tried to apply a discount on my ressie for July and the CM told me that because my ressie is over 14 days, no discounts can be added, even AAA.
I was not a happy camper, so I had her drop a day and try to put AAA on it, nothing.
The way things are going, it might just be more than one day I hack off that ressie if I don't find something to apply to it soon.
