Add dishwasher pods to the list. It’s literally just smoke and mirrors for nearly the same formula as powder, only less of it per package. All those fancy colors? It’s die. It’s the same formula across the entire pod. So… Yep: more cost, more waste, and it has some reasonable downsides. For “convenience,” since I guess deciding how much to put into the tray is just too much work.
