How can McDonald's turn a profit on these outrageous deals?
The short answer: they probably aren't, at least not yet.
McDonald's is probably losing money in the short-term in order to gain customers over time, Sean O'Keefe, a professor in the Food Science department at Virginia Tech, told Business Insider.
"I expect this is a loss leader to get people into the store," O'Keefe said.
The fact that drinks aren't included in the deal will also help McDonald's make money, O'Keefe said.
Soft drinks cost typically cost just a few cents to make, but sell for about $2.
"I expect they break even with this or have a small profit, but the promotion gets McDonald's on people's radar and in the door," he said. "There appears to be a lot of buzz for this promotion...so it certainly is advertising to boot."
McDonald's profits slipped during the first-quarter of this calendar year, as sales declined by 1.7% in the US.
