I pretty much ignored the candy and went straight to the bottled sodas because I stopped in here on my way to Pittsburgh specifically to check out the bottled sodas.
The selection is heavy on the root beers and ginger beers, but they have a decent selection of colas, cream sodas, and other types of soda pop (they say there are over 150 varieties to chose from). The prices range from $1.65 to $2.95 per bottle and it probably took me about twenty minutes or more to narrow my selection down to 14 different sodas. You also get a 10% discount if you are buying more than six bottles.
They also have several tasting events per year where you can compare different root beers or ginger beers, etc.
