I live about 2 hours north of there, so I have an idea of what's there.
Coke is CCE, they have the same stuff we have up in eastern MD, for the most part.
Pepsi is Pepsi Bottling Ventures of NC. Standard Pepsi lineup plus Dr Pepper. Things were a lot more exciting when they were indie Pepsi Delmarva - they were a huge DPS bottler.
Canada Dry Delaware Valley is the distributor of the rest of the DPS stuff, vitaminwater, and a few of their own brands, except I don't know if the branch down there carries them. They have a line called Rock Creek, and another called Frank's. They also bottle the Canada Dry flavors.
I live in northern Delaware, but I rarely go further south than Dover, which is in the middle of the state. I've seen the Rock Creek and Canada Dry flavors down that way, but only in a 7-11. They don't seem to sell those lines in grocery stores. Most of the 7-11s up here carry them - some flavors are only 20oz, some are only 2L, some are both. None in cans, though. They also carry Tahitian Treat and Pennsylvania Dutch Birch Beer -
Welcome to PA Dutch! Homepage from USA Beverages, as well as the Alex's Lemonade Stand flavors in 20oz -
