par
In "par carte", "par" marks the card as the payment method. It does not mean the card by itself; the full expression gives the payment meaning. Use "payer par carte" when saying that payment will be made by card.

avez
In "Vous avez besoin d'un reçu", "avez" is the form used with "Vous" in the expression for needing something. The meaning of needing comes from the whole expression, not from "avez" alone. Reuse "Vous avez besoin" when asking whether someone needs an item.
besoin
In "Vous avez besoin d'un reçu", "besoin" is the central word in the expression used to say that someone needs a receipt. It works with "avez" and the following "d'un reçu". Use the same expression before the item that is needed.

reçu
In "d'un reçu" and "le reçu", "reçu" means "receipt". It is first the item the customer is asked about and then the item to be put in the bag. Use it with "d'un" when referring to a receipt that is needed and with "le" when referring to the identified receipt.

s'il vous plaît
The whole expression "s'il vous plaît" politely turns "Mettez le reçu dans le sac" into a request. "s'il" contributes the opening "if it", "vous" refers to the person or people addressed, and "plaît" contributes the idea of being pleasing; the parts are normally learned together as "please". Use it when making a polite request to a shop employee or another person.
