OK, the phone could send you one of two main routes. North Exit to rte 528 to I-4, or South Exit to rte 417.
Taking the North exit to 528, there is a convenient Publix at 9930 Universal Blvd, Orlando, FL 32819. Its easy on/off.
Taking the South exit to 417, there's a Publix at 8145 Vineland Ave, Orlando, FL 32821, and another one at 29 Blake Blvd, Celebration, FL 34747
I'm giving you the Publix supermarkets because that's where we shop. There are also Walmarts and Super Targets in the area. You might check Google Maps for them.
