Publix is by far the cleanest and most organized grocery store I have ever been to. They are competitive in their prices and most of them will accept their competitor's coupons. They often run buy one get one free deals and it really helps to stock up on those paticular items!
The produce department is the only thing I think is sometimes lacking. I guess it depends on their shipments of fresh fruits and vegetables.
Their meat department is always stocked and the meats are very fresh.
The deli deparment offers Publix brand deli meats as well as the national brand Boar's Head. Be prepared, the deli si the busiest place in the store!
Their customer service desk is always very helpful. They do payroll and check cashing there for a very minimal fee.
Publix is the only place I care to shop for groceries.
