Harry the shopkeep

Harry Potter somehow finds himself in fairy tail sometime after the defeat of Voldemort. One there he opens a magic shop.

Whether he walked the the vail of death as a portal with all the potter and black resources plus a small community of house elves in an expanded chest filled with almost every kind of plant and ingredient or he tried teleporting drunk and only has what is on him is up to you, have fun with it.

(super enchanted objects, epic potions and flying brooms have fun with all kinds of magical products, maybe even pets)
