Most of the dubs I know are baking unleavened bread and getting the red wine.I thank my lucky stars that my wife is practical enough to say that since we are not anointed there is no point.
What to do with it afterwards? I guess it is up to the individual. When I conducted a memorial one year I found an article that directed what sort of wine to buy and bread to have. I just bought a bottle of red plonk and a packet of Jewish matzohs.. keep it simple.
After the memorial some friends came around and we had a nice supper with red wine cheese and matzohs.
