Hi,
a month ago we released a plugin for tier prices. This can be used in order to customize the price calculation based on quantity the user wants to purchase. For example one item costs 10$ per piece and for ten or more items it cost 9$ per piece. This can be configured based on the product’s active channel and automatically updates the price calculation live in the product view as the customer puts more and more into the cart.
If you are interested in the code, you can find it on github or get it with composer: brille24/sylius-tierprice-plugin.
