Perhaps Harry enters the potion shop and is surprised by the new and improved Draco who has turned over a new leaf. Draco shows Harry around the shop, introducing him to new potions he has created, and they end up having a civil conversation that could lead to a new friendship.
Maybe Harry goes there to buy a special potion for his next adventure. He might be greeted with a cold stare from Draco at first, but then Draco realizes it's just business.
In the fanfiction, it could be that Harry is forced to go to Draco's potion shop because it's the only place that has the rare ingredient he needs for a potion to save a friend. Draco, on the other hand, might try to overcharge Harry, leading to an interesting negotiation.
