You can also apply a promotion rule to give a price reduction. For example, you may offer a 20% price discount for wholesale members or apply a time-limited flat discount.
You can also use XSL to write more complex promotion rule. The expected output should return the calculated promotion price to charge. Promotion rules are always applied after product modifiers. The Storefront comes with several pre-defined rules that you can simply modify the values without needing to know XSL. To learn more about XSL, please see the XSL Transform section.
