One of my favorite online stores for food related things is Whammy! Industries. They have a large assortment of food/recipe zines and they also sell tons of other food related things like Duct Cakes (cakes made out of Duct tape!), kitchen gear like recipe cards and accessories. All of the items are made by independant crafts people so when you buy, you are supporting small businesses and artists.
In the interest of full disclosure, Whammy! also sells my zines, but I have been a fan of a lot longer than that and my items are not on consignment.
