Hi Ethan, thank you for providing your feedback on promo codes. At this time we're not planning to allow for stacking of codes on top of discounts, but we are collecting this feedback in case anything changes in the future. Thanks!

Ryan, you'll be happy to hear that the Promo Codes feature was released this morning actually (great timing!). You can access the feature by going to Settings -> Billing Settings -> Promo Codes. Please reach out if you have any questions or check out our Knowledge Base articles. 

Good morning! Promo Codes are actively in development and currently in an Early Access phase for initial testing. If you're interested in joining the early access group, feel free to let me know and I’d be happy to share more details.
