Fortunately my wife has been very supportive of the hobby, and that I have to do it anyway. Two things I am doing that help... First is a compact storage system, you can fit quite a few in the plastic organizers, even doubling them up in the slots. If one kept the boxes and all it would be a closet full. Second, she plays along with the soap scents. I ask for her ratings and preferences. Sometimes when I read scent descriptions to her she tells me I have to order that one. To which I say, "yes ma'am!"
Mine too. She even allowed me to convert the guest bathroom into my den, though it has cost me a few Coach purses.
