Hi there @Tobi Chapman,
Welcome to the Community! Happy to help!
Great job thinking of incentives for your customers! While, our platform does not support the functionality of stacked coupons as any Shopify coupon generated in Klaviyo will be one per order and cannot be stacked, I am happy to submit this as a feature request as I know other users have mentioned the advantage of this feature!
Here are some other resources in Community to investigate what incentivizes your customers!
Thanks for participating in the Community!

Hey Klaviyo users!
Thought I’d share a solution I’ve built that resolves this problem (one I was dealing with also).
I built a Shopify app that automatically combines Klaviyo coupons to any/all of the combinations of your choosing.

Theres a 7 day free trial for anybody wanting to trial it out.
Thanks! Brad
