A French Phrase for Asking whether an item can be exchanged: "Puis-je l'échanger ?"

"Puis-je l'échanger ?" means "Can I exchange it?" and it's the basic French expression used for asking whether an item can be exchanged. It's very handy when shopping for clothes and shoes. To answer, you can say something like "Oui, avec le ticket de caisse." (Yes, with the receipt). You can keep the conversation going by reacting with something like "D'accord, je le garde." (Okay, I'll keep the receipt).
