This bundle decorates the sylius.order_processing.order_prices_recalculator service. If you wish to use your own order processor or change its priority, you could register a compiler pass.

Usage

First of all you have to set up a product with as many variants as you want. Then in each of these variants you can set the tier pricing based on the channels. The table automatically sorts itself to provide a better overview for all different tiers, you configured.

In the frontend the user will see a nice looking table right next to the "add to cart" button that shows the discount for the different tiers like so:

Creating data

You can easily create the tier prices with fixtures like that.

sylius_fixtures:
    suites:
        my_suite:
            fixtures:
                tier_prices:
                    options:
                        custom:
                            - product_variant: "20125148-54ca-3f05-875f-5524f95aa85b"
                              channel: US_WEB
                              quantity: 10
                              price: 5

For this the products need to be created first and the product variant must also exist.
