Filch's Emporium
It will become monotonous and repetitive to declare this space as tight and restrictive. It was so claustrophobic that, after wading through the sea of TMs, I accidentally took the exit to the backstage area. But the merchandise is worth the struggle -- and while I don't have all the prices memorized, here are some items and prices to give you an idea.
The most expensive item in WWoHP, according to a well-informed TM at Filch's is... Wizard's Chess at a whopping $400. No, it doesn't move on it's own, but it is a highly detailed item. ...Second, is... House Chess; decorated gold and silver (Gryffindor vs. Slytherin), the chess set is quidditch-themed and priced at $300. ...An item that surprised me at its expense is the... Marauder's Map. It's encased in a glass frame with hinges, but it is elaborate, extensive, and exactly like one would imagine it -- minus the footsteps of living beings. $64.95. ...One final unique item, that the TM took me to the cash register to check out, was... Mad-eye Moody's staff -- this would be an amazing thing to have if it wasn't so damned heavy! But it was a really cool item; I did not request the price.
The regular post-ride shop items can be found, many of which tempted me. Sirius Black wanted-poster coffee mugs, Bellatrix t-shirts, stuffed unicorns, owls, phoenixes, Crookshanks, and Scabbers (who is appropriately missing a toe). Hogwarts journals, beer steins, towels, pillows, throw rugs, and clothing. Even Voldemort action-figures (more like a doll...). To quote the lawyer from Jurassic Park, "We're going to make a fortune with this place!"
Tight quarters will be the chief complaint of every shop and space in WWoHP, minus the Three Broomsticks, which will be the topic of my next post. But Filch's is wonderfully themed and contains many items unique to it in WWoHP, and the staff were very knowledgeable about their shop already.
