Price Update Hook

Hi. Thank you for this amazing plugin. I’m hoping you may be able to assist me with something. I would like to hook into the pricing updates function in order to modify the returned price before it is returned. My use for this would be to potentially add or subtract values (based on coupons, discounts, etc). For example, after the price rules have been applied, I would like to then apply a $10 coupon (I already have the code for this). I would just need to be able to pass the product id or object and price. Please let me know if there is some hook or filter I can use. Thank you.
