Sable makes efficient work of shopping with the list she and Henn made. She makes a quick run through the Typical Grocery Store for the spices, sides, marshmallows, and miscelany, then hops a portkey to some foreign fish market at dawn to haggle a few (hundred) clams with cash as the boats are still tying themselves to the dock.
She returns to the lagoon barely two hours from when she left, dragging a wagon full of fresh seafood and a few bags of groceries. Everything she bought is part of the meal, so she doesn't bother doing anything but weighing down the grocery bags with a couple of stones to make sure they don't blow away before they can dispose of them properly... probably tomorrow morning.
