Short way of saying: "More expensive" Toiletpaper. 2-ply standing for 2
layers. Commonly cheap versions of toiletpaper (or paper towels or whatever) are made of 1 layer of paper. More expensive,
luxury versions are made up of 2 or up to 3 layers.
Respectively 2-ply or 3-ply
In this economy it's hard to balance money to be spend on daily needs and
groceries in general. Because of that we had to switch from the comfortable 2-ply toiletpaper to the cheaper 1-ply. Another $3 a month saved.
