Nobody, anywhere, simply has magic items on shelves in shops. They'd be too tempting a target for thieves, plus 99% of the populace would never even be able to afford a frickin' Potion of Cure Light without saving every spare copper for like a decade. You'd have to get an item custom-crafted, providing half up front then the rest on completion ... assuming the crafter is even willing to make it ("A nine lives stealer? Aw HELL no.")
I run it much the same, for any settlement of sufficient size. Especially if there's a mage college or major temple of some kind in the area. "Need some wands of cure light wounds? Sure, we can put you on the waiting list and have some of the acolytes make those for you in say, 6 days."
