How does Shopify prioritise discounts that are in conflict?

[MVS-ONE]

If I have the two following discounts active, but are set to not work with other discounts.

1. $10 off when 3 items from Collection A are in the cart

2. $20 off when 4 items from Collection A are in the cart

How does Shopify prioritise discounts in the case that 4 items are in the cart, since both 1 and 2 are valid here? In practice, it seems to be 2 and I assume it choose the valid discount with the higher value, but I'd like to confirm that, since I'm going to be runnings a store with lots of these types of rules.

Hi @MVS-ONE ,

I think you can refer to this documentation about discount combinations in Shopify: https://help.shopify.com/en/manual/discounts/combining-discounts.

It provides many examples that you can check and apply. 

Sorry for misunderstanding the question. I think we need to conduct an experiment for this case.

No you were right. That doc does mention discount priority.

> If two or more discounts are applied, but can’t be combined due to the discount combination setting or the content of the cart, then the best discount for the customer's cart is always applied.
