Does Vilmos Bartok sell unique items? Little shop of dreams Quest

I'm in the very easy Little Shop of Dreams quest, and I can make Bartok (the herbalist) close his shop. The problem is that the shop close forever, so maybe I should buy all items he sells....but I haven't enough money
Does he sells unique items, or I can find in other shops?
I can also conclude the quest without closing the shop, but wonder about this part in the wikia

If you decide to allow Vilmos to continue selling his incense, the quest will be marked as succeeded, though Mathilda Szabo won't be pleased. However, upon completion of mandatory quest At a Crossroads: Vernon Roche or At a Crossroads: Scoia'tael, the quest will fail.

He has some recipes that are hard to find otherwise. The one I always buy from him before shutting him down is Virga.

Thanks. But what about not close it? Can I succesfully conclude the quest without make it close? On wikia, like I said, seems that if you don't close the shop, later in the game it results not concluded.

No, you can intentionally fail the quest by not closing the shop, but you cannot succeed by taking Vilmos Bartok's side against Matilda Szabo. An unfortunate omission, but there it is.

The best sequence is:
- Do your own shopping
- Get the recipe for Scent of Incense
- Shut him down
