coffee and charcoal and cakes

I've been stymied in my attempts to purchase a simple melitta one-cup drip coffee cone and filter and a bag of natural lump charcoal. We were also greatly dismayed to discover that the flour section of cub foods is completely dwarfed by the size of the cake-box-mixes. And they didn't even have a basic type of flour, pastry flour, which is used in many, if not most cake recipes.
