Lots of good cheap wine - You can get magnums for under $12 of Concha y Toro, Lindeman's Cawarra, Bin 50 shiraz or Bin 45 cabernet, or Glenn Ellen. Clos du Bois (little pricier and small bottle), La Crema, Ruffino chiantis - all yummy.
I think for mixing, Smirnoff is fine as is Jack Daniels.
Have fun and don't drink and drive
