WooCommerce Timer Coupon Plugin

I need a coupon plugin which integrates with WooCommerce. I want to be able to send people to a page after they have opted in to my email list, which has a timed coupon on it. If you have a look at AppSumo, you'll see exactly what I'm looking for, after you purchase a free product: As soon as they enter the page, the timer starts running down, from whatever I set it to. 30 minutes, 1 hour, etc. As soon as the timer is up, the coupon code needs to become invalid. I guess it would need to be different for everyone who sees the timer. The coupon would need to be able to function like a regular coupon in woocommerce, so that I can change settings like which product(s) it works on, whether it's a % discount, or a $ amount. I would like to be able to enter this onto a page as a shortcode, potentially with the ability to automatically apply the discount when clicked on. Thanks, Josh Dunlop
