Hi @the permalinks, 

Fun situation! Happy to help!

If you want this notification and process to happen in your checkout process, where if a customer has over $120 in their cart they can choose what free gift they want or if they’re within a $50 range to reach the $120 mark you would encourage them to spend more, then this would be something you would need to set up in WordPress’s backend. However, if you wanted to send them a notice or discount code after their checkout process, then this would be something you can set up in Klaviyo!

Thanks for the participation in the Community!
