When you buy a piano in a music store, it is usually delivered to your door and placed in a designated place at home. Look after the piano first when you buy it, and then the store will arrange delivery. As for who will bear the freight, tell the store specifically. If you buy a grand piano, the store will also install it (the expenses will be borne by the store).

As for buying other musical instruments, there is no need for the store to send them. Of course, if the purchase is large, or the customer is really inconvenient, you can also ask the store.
