# Function limitations by Shopify

### Restrictions imposed by Shopify 

1. You can have a maximum of 25 automatic discounts active on your store at one time. This means that a maximum of 25 automatic discount codes can be applied on the same order.
2. Customers can use a maximum of five product or order discount codes and one shipping discount code on the same order.
3. Discounts can only be combined on orders that are made through the Online Store and [Shopify POS](https://help.shopify.com/en/manual/sell-in-person/shopify-pos/discount-management/combining-discounts).
4. Products that are part of a [Buy X get Y](https://help.shopify.com/en/manual/discounts/discount-types/buy-x-get-y) discount are ineligible for further product discounts. If a customer enters a discount code that applies to products in a Buy X get Y discount, then the Buy X get Y discount is removed and only the discount code that the customer entered is applied to the order.
5. Discounts created through Shopify functions (regardless of automatic / coupon based) will only apply to the first checkout order on subscriptions.
