for sure, because if they don't, they'll stop selling it.
you do know that unsold chicken gets used in their salads and other ready to eat dishes, right? in my local store, they even started selling 6 pack of the legs and thighs part of the unsold roto chicken and those are flying off the shelves fast....
with their procurement powers, you'd be surprised on what's their cost to buy the chicken.
The rotisserie chicken usually sells out within an hour of closing. There's usually a line waiting for the last batch of the day.
