Not always the case, as sometimes PPU stands for Porch Pick Up - where the item is left on the porch of house and buyer just comes and picks it up, and if paying leaves payment at agreed location on porch.
Very confusing that PPU has two very different meanings!!!
Sorry, they are gone. Someone stole them off the front porch and I could not even donate to this community. (They didn't take the steal the "steel boatbuilding" if you want that... )
