I love this sub! I canceled only because I bought several of the non-sub boxes and my House of Usher boxes are kind of piling up! I would highly recommend! All the boxes I've gotten have had a nice mix of scents (except Alice which was advertised as fresh/fruity).
With that said, it's definitely a guess when stuff will get shipped. It's usually later than advertised and labels are created several days ahead of time which gets frustrating.
Lately she has put a poll on Facebook to let people pick the theme. I haven't seen one recently though.
