Using Shopify POS, you can apply custom discounts to line items, or to the whole cart. You can also apply custom discounts to items you're exchanging.
If you've set up automatic discounts and discount codes in your Shopify admin, then you can add and combine these discounts in the Shopify POS cart. You need to make sure that your discounts can be combined.
