Oh yes, many of us have. Quarry got a lovely little case for her collection but danged if I can recall where. My collection has been everywhere-- dark closet, one of those lean against the wall shelving units, and currently lives in my (former) breakfast room china cabinet. Light is the enemy of fragrances, but I like to look at my bottles and see everything when I choose a scent. Hiding them away in a dark closet robbed me of a great deal of pleasure. The leaning shelves left them vulnerable to my cats.
I'd say start at Hobby Lobby. I frequently notice sweet little cabinets there at a good price.
