Vente-Privee has Surface to Air on the site today. This is much of the same stuff STA has had on sale the past couple weeks, but the prices are a little better. (Full disclosure - I work here, haven't posted anything before, but this seems like a sale that Styleforum would find interesting and our prices are great)
I sometimes leave half a 750 or bomber in the fridge over night. I just recap them or find an odd wine cork lying around.
This works with low carbonation/high alcohol beers fine. Usually I do it with an Impy stout or barley wine. Open and pour out half. Cap right away and back in the fridge. Opening and closing more than once loses the carbonation.
