With it, we can evaluate whether a given condition is true or false and execute different blocks of code based on that evaluation. For *example*, check if the `order.total_price` variable is greater than *150* and dynamically apply a discount coupon based on the value: ```twig theme={null} {% if order.total_price > 150 %} Current Price: {{ order.total_price }} Discounted Price: {{ (order.total_price * 0.85)|format_currency(order.currency|default(shop.currency_code)) }} _(15% discount applied)_ {% else %} Current Price: {{ order.total_price }} Discounted Price: {{ (order.total_price * 0.90)|format_currency(order.currency|default(shop.currency_code)) }} _(10% discount applied)_ {% endif %} ``` In this example, we check whether the `order.total_price` variable is greater than 150 using the `{% if %}` directive. If true, a 15% discount is applied, displaying the new discounted and formatted value. Otherwise, the `{% else %}` directive is used to apply a 10% discount, also showing the updated and formatted value. In both cases, the code displays the current order value and the discounted value, along with an indication of which discount was applied. **Sample output from the code:** Example `if/else`
