Shopify Scripts: Rejected discount is not considered

Solution:

I don't think you need to reject the discount code at all. You can simply add a condition that controls when the discount is applied, for example:

if Input.cart.discount_code&.percentage
    discount = Input.cart.discount_code.percentage / 100.0
    discount = 1.0 - discount.to_s.to_f # there's probably a better way to do this... but :) 
    Input.cart.line_items.each do |line_item|
      if line_item.variant.skus.include? '3033358' # check if variant SKU is 3033358
        line_item.change_line_price(line_item.line_price * discount, message: "Applying discount code: " + Input.cart.discount_code.code)
      end
    end
end

Output.cart = Input.cart
Copy code

This way you are avoiding hackish solutions. Instead of checking for skus you can check for tags, title, and so on.

You can also create a null variable, run some for loops in advance and set true/false flag to that variable and use it in your if condition. Either way, the direction of rejection is the wrong way and personally, I have used it only once to prevent customers from abusing a very complex campaign (which was an exception).
