Hyde here from Shopify. Great question!
It looks like you're trying to create an automatic discount where if customers spend over a minimum amount they get a free gift. We have a guide on that but here is how you set the conditions:
You've clearly set a minimum amount in your own discount for RM 68, which is great! You've also stipulated that a customer needs to buy a product from either the homepage collection or the virtual roadshow collection:
What's a little confusing is why you've created a product that is titled "Free gifts with purchase above RM 150", but you've set the minimum amount to be RM68?
You've also said that if a customer also adds a product from a particular collection to your cart, they will get it for free:
It looks like you have tested this out by only taking one product through to checkout:
The important thing to remember is that this free product will not be automatically added to the cart. The customer needs to manually add this product to their cart and it will only then be marked as free. So try adding the product and one of the qualifying discounted products to the cart and see if the discount is automatically applied.
I hope this helps, let me know if you have any further questions!
All the best, Hyde.
