Shipping beer from Belgium

Does anyone have any tips on shipping beer from Belgium to California? I brought a couple of six packs of Westvleteren 12 home in checked luggage last year, but this year I would hope to bring back 2 cases. I would prefer to have it shipped back by common carrier rather than try to get it all onto my flight. I wonder if any consumer has made an arrangement with a liquor business with an alcohol shipping license?

Etre Gourmet and Belgium in a Box have drop offs in Belgium. I would recommend one of these services.
