Foodstuffs?

What is the plan for procuring edibles and beverages for the bachelor weekend? I assume the keg is a go, but we made need additional spirits and whatnot. I'm in town on the 13th and would be down for a Costco expedition if anyone's interested. Otherwise, I guess we can do the customary stop en route to the party. Might be more cost-efficient to do it beforehand though. Let me know...
