Cobb & Webb's is a shop in Knockturn Alley, London, where one could purchase items related to the Dark Arts.

To some people, the shop’s name makes no sense, but it does to the White family. Its front isn’t that big, mostly having a few shelves showing off only very little artifacts mostly because their business is about finding things, whatever it is, things that wizards might want. Of course, everything comes with a price, but they are particularly good finders at whatever objects might pique your interests. They have no particular affiliations but not a lot of people like to venture there afraid of the price they might have to pay in regard to what they are looking for.
