This is me but I am finding some losing their scents. I try to use them up when this starts to happen. I dump them if they lose all their scent. They really don't serve a purpose to me.I have a hard time getting rid of soaps so I just let them all accumulate. Very often I'll try one that I hadn't in years and find it works different and better than I had originally thought, sometimes due to weather, a move(water softness), or just plain preference has changed. A lot of soap tastes are subjective so what you might like this year could change in a few years. That's the biggest reason I keep mine around.
I agree with @dfoulk on his choices. I have not tried grooming department but have the others. They are all top and mostly all I use.
I have not been purchasing just for scent but for tier, lately. I would use lessor tier, if it wasn't too much, but have issues understanding some scent descriptions. Although a top tier, grooming department is one I cannot really read and know what I'm getting.
