Automatic Discounts option is available by default in ecwid. You can visit the URL https://my.ecwid.com/store/storeid#discounts (replace storeid with your store ID).
There are three types of discounts possible i.e
You can add discounts based on subtotal i.e if subtotal is greater than 1.
You can add discount based on customer group i.e if the customer based on specific group.
Note: The user needs to be logged in for this discount to be applied.
This works in a combination of subtotal and customer groups.
