You get two cash receipts: one immediately after paying for your order and one after picking it up. The second one is broken down by products.
The amount in the receipt is displayed in the order currency. You can view the order currency when placing the order. To do it, click Learn more next to Total cost in the cart or click Total on the checkout page. If you’ve already placed an order, click Learn more next to Total in the My orders section on the order page.
You don’t need a cash receipt to return the product.
