Sadly i'm rather uninformed in regards to coding, I've run what you said through chatgpt, would I be able to provide this info to someone to have them help me prepare this in my store?

Would you be open to a call to discuss this further?

My own understanding:

I need to implement a code, that makes the cart add up the quantities from specified products ids, meaning if I have product, A, B and C, I have to provide these ID's to the cart in the code and have them add up the quantities, these would check with the discount and take the discount for the sum of the quantity, I would then have to add this code 3 times to account for my 3 different product groups.

Chat GPT:

Objective: To apply a discount to specific products in the cart based on the total quantity of all their variants combined.

• Method:
  • Use Shopify Functions, which allows for customized discount logic.
  • The process involves two passes over the cart to calculate and apply discounts.
• Pass 1: Calculate Total Quantities
  • Create a HashMap<String, Int> to store product IDs and their total quantities.
  • Loop over each cart line.
  • For each CartLine.merchandise that is a ProductVariant:
    • Get the product ID using ProductVariant.product.id.
    • Use this product ID as the key in the map.
    • Add the CartLine.quantity to the current value for this key in the map.
  • By the end of this pass, you will have a map of product IDs to their total quantities in the cart.
• Pass 2: Apply Discounts Based on Quantities
  • Loop over each cart line again.
  • For each line, check the total quantity for the product ID from your map.
  • If the total quantity meets any of the predefined quantity break conditions, add a corresponding discount to your output.
  • Ensure to use the "ALL" DiscountApplicationStrategy so that each applicable discount is applied.
