Recipes are also item drops otherwise they wouldnt appear in chests!
on work as TM and break up gangs, level 450 recipies drop as product drop... how else you can explain reports with people finding 2-3 of those recipies and an item!
so laundry baskets and level 450 recipies shouldn;t be counted to item drops
If I remember correctly then recipes are a 3rd drop category, so they aren't an item drop or a product drop.
