I just received my package.  I bought the butterbeer and orange groves in candle form.  They smell wonderful, not overpowering.  They both smell like they are supposed to.  I'm thinking I might make shepherds pie tonight and pretend I'm in the Wizarding World.
I bought 4 shower melts.  Walt's Office and Wilderness Resort both have that woody smell, but Walt's does smell like leather.  Both are pretty great.  I don't really care for the Haunted one, but I might change my mind when it's in the shower.  It smells sort of like incense in church (I'm Catholic).  The Polynesian just smells fresh to me.  I can't really pinpoint a fragrance.  I think that one will be great in the shower.
I bought 4 air fresheners.  I'll report back as we open them.
Update:  we opened the Banshee air freshener.  It is very powerful.  It does smell like the ocean and freshened the bathroom and the hallway.
