7-eleven Bundle Deal with App – $.91 TODAY ONLY YMMV? $0.91

The cashier at my local store pointed out this deal this morning. They had a display on the counter to advertise it.
TWO Nature Valley Granola Bars
TWO Corn Nuts
ONE Amp Energy drink
The total of $.91 included PA Sales Tax. If this is a Nationwide promo, then clearly the final amount would vary.
