I don't think there's much of a DEAL with them. They all sell alcohol, some have better selections than others. Some specialize more in craft beer, others have a huge wine selection. Prices definitely fluctuate but they're all pretty close to stay competitive. You might like the owner of one better than another and they might be able to special order for you.

You'll have to start checking out your local stores and pick one you like. I don't know the Madison area stores but I'm sure others will have suggestions.

good luck! CHEERS
