@Nicole2346 What do you mean, "towards the end"? Any discounts you set will automatically be shown to guests and the total price with the discount is charged to guests when they book. (They can often choose to pay half up front and half about a week before check-in, but that isn't anything hosts control)
As an aside, your listing needs work. 3 photos of the outside of the property isn't a proper photo gallery. You need photos of the inside of the suite, the bedroom, the bathroom, all of it. That's what guests want to see. 3 long-range outside shots won't get you bookings.
Also your listing description is scanty. It appears that this is a private suite in the home you live in. Some wording about being on-site hosts is needed, as well as information about common spaces you share with guests, such as the yard and anything else.
The more info you provide, the better, although it's always best not to be unnecessarily wordy, while covering all the bases. You want to avoid guests arriving with inaccurate expectations.
