Prices can fluctuate from location to location, and according to the app of one particular location, a four-piece order is priced at $2.29 on the Dollar Menu.
Additionally, a six-piece order costs $2.99, while a 10-piece order totals $4.79, making the latter a better deal when ordering from this particular location.
Perhaps the chain has caught wind of the hack and altered the prices to thwart deal-seeking customers, or maybe you have to visit the physical location to make this hack work.
