Buying musical instruments for a stage play

Few days ago, there’s a sale of Yamaha open hole student flute in a store nearby. While I stepped in the store, I asked the sales person if they have available musical instruments that I needed for a stage play.

Then, the sales person told me that I can choose from their selected products under the sale. But she can give me 10% discount on our agreement, if I buy that flute.
