How can I add a discount that is time limited?

Specifically, I'd like to automatically add a 5% discount to a product which a costumer pays in full by the end of August. I would like the discount to automatically end in September. How would I add that discount and edit it for future changes? Thanks so much.

Are you using a payment integration (Stripe/Paypay/etc)?

If so its easy:

How To Add Coupon Code in the Payment Form 

Thanks! I am using PayPal and I considered the coupon option. It might work, but it is a bit complicated as well.

We are a preschool and are offering 5% off of paid in full tuition for the year if paid by August. The products are separated by days (M-F) as well as by term, so I'm trying to decide how I could manage the percentage off. The five percent could be added to the total, but because of the nature of the products it would be hard to make sure that the parent chose the full year. I guess I could just offer the coupon code and use the honor method to make sure that the parents chose the correct products. I can't see a way to make it conditional without it getting really complicated.

Thanks for your help!

Sure, anytime @ScuolaItaliana. Just to clarify, the guide suggested by my colleague is a way to add a Coupon Code to your form. Yes, this will work for your needs but it's not something that will automatically end on its own. You'd have to remove the coupon code when the time comes.
