The Place: Rogan Store
The Price: FREE, must RSVP: firstname.lastname@example.org
The Details: While it doesn't explicitly say the booze is free it is sponsored by a vodka brand and takes place in a store. Store parties and booze sponsored events almost always have free booze so with both I think we're good to go here.
