Magento2: How can update the product price using before plugin

Question

I want to update the product price using plugin and I tried the afterGetPrice() plugin its working fine in normal case but showing wrong price calculation when catalog price rule applied, I want to apply catalog price rule before the plugin execution. I tired the below code :

di.xml :

 <?xml version="1.0" ?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <type name="Magento\Catalog\Model\Product">
        <plugin name="change_product" type="Vendor\Module\Plugin\Product" sortOrder="1" disabled="false"/>
    </type>
</config>

Product.php

public function afterGetPrice($product, $proceed) : float
    {
        return $proceed+111.55;
    }

I want to apply catalog price rule before the plugin execution.

Answer 1

You should use afterGetFinalPrice instead of afterGetPrice, that way all calculations of prices will be done.
