The Charges section of the Rental tab lets you add fixed amounts on top of the per-day rental price. There are three separate charge fields. Any charge left at zero is ignored entirely — it does not appear to the customer and is not added to the cart.
Each charge has its own description field directly beneath it. Text you enter there appears under that specific charge on the product page and nowhere else. The deposit description appears under the deposit, the insurance description under the insurance, and so on. These fields are independent of each other.
The Comments field is free text that appears with the rental options on the product page. Use it for information that is not a number: what is included in the rental, what the customer should bring, how collection or return works, and any other practical detail the customer needs before booking.
