Tagging @Winddancer re the change of 'address' on the little wooden disc that Isys gave to the children.
The shop is 'Needful Things', run by Ann Other. Absolutely an alias. There is no description for the shop further than the name (which was shamelessly 'borrowed' from Stephen King, to whom all credit is owed). If you've read his novel of that same name, then you might have a sort of clue what it in store (pun, sorry). Well, a slightly less terrifying version, because after all, this is Gondor, not Mordor.
