Minimum spending for Dynamic coupons

Hi guys,

I made dynamic coupons using Klaviyo and connected with my website. How can I set up the minimum spending, for example if you spend $50, then you can use the code. Is there a way to do on squarespace?

also, when customer use one of these dynamic coupons, they can not use other coupons I believe? On top of the dynamic coupon, how can I still offer them free shipping for orders over $150? I know that you can set free shipping system without making a coupon code if you’re using the premium plan, but I’m using the basic ecommerce plan and I want to know if there is a way to offer customers both the dynamic coupon and the free shipping(over $150).

Thank you in advance!
