I've been following chicken prices very closely since 2011 because you can use price of wholesale chicken to negotiate better deals at places like Popeyes. It's not rare for me to get Popeye's $5.00 box for $2-3. I typically ask for a manager politely and ask if they're familiar with the going rate of chicken on the wholesale market, (they're usually not) and I go on to explain that their chicken is grossly overpriced in relation to the market.
The managers sometimes push back but that's when I casually threaten to call corporate and the manager usually asks me not to and discounts the order.
I've probably saved in excess of $100 in fried chicken using this strategy but it looks like I won't have to anymore if the fast food chains adjust their pricing accordingly or offer new specials.
