Sonic is offering a free "CrosSONIC" breakfast sandwich with a purchase of a large drink. It's an egg and cheese croissant with your choice of sausage or bacon.
HERE is the link to fill out the form so the coupon can be emailed to you. The coupon expires 10 days after you print it, so make sure you are heading to a Sonic soon. This offer is good through the month of May.
Thanks Bargain Briana.
