Does anyone know of any apps that can do this? Offer automatic discounts based on total cart values, for example: reaching $ 100 we offer 5%, reaching $ 200 - 10%, regardless of the number of items repeated or not.
Like this, but applied in cart total purchase
I recently came across an app, Kart Discount which worked for me to apply different automatic discounts at the same time. They can help you to do this customization on your store. Download the app (https://apps.shopify.com/discount-coupon-field-in-cart-page) & contact their support team, they are really fast!
