This fast food joint is giving away free breakfast sandwiches in May

Subway announced this week that it will be giving out free breakfast sandwiches during the entire month of May — but there is a catch.

quick-serve chain Subway has done well because of deals like the $5 footlong

.

To qualify for the free deal, customers are required to purchase a sub for lunch, AND they have to complete their order before 9 a.m.

Under the buy-one-get-one offer, customers who purchase any sub (6 inch or footlong) before 9 a.m. will receive a free 6-inch breakfast sandwich.

“Everyone knows the importance of breakfast to help fuel their day, that’s why this May we want to make your morning even better by offering a free Subway breakfast as a reward for enjoying any of our millions of fresh, handcrafted sandwich combinations,” said Chris Martone, executive chef for the Subway brand. “Our robust breakfast menu has something for everyone – whether you’re in a rush, on-the-go, or sitting down for your first meal of the day.”
