I haven't found the Coco-Wet but after some googleing found the seventh generation dish soap i think. - here-
http://www.drugstore.com/seventh-gen...lear/qxp145457
for $2.21 a bottle - I haven't bought from them.
If this is the correct dish soap it says free shipping on $25 dollar order. And if I understand right can be used instead of the Coco-Wet.
