Body
<p>After digging a bit into Magento's core code, I found that you need to use <code>$item->getProduct()->setIsSuperMode(true)</code> in order to make <code>$item->setCustomPrice()</code> and <code>$item->setOriginalPrice()</code> work.</p> <p>Here is some sample code you can use within an Observer that listens for the <code>checkout_cart_product_add_after</code> or <code>checkout_cart_update_items_after</code> events. The code is logically the same except <code>checkout_cart_product_add_after</code> is called for only one item and <code>checkout_cart_update_items_after</code> is called for all items in the cart. This code is separated/duplicated into 2 methods only as an example.</p> <h3>Event: checkout_cart_product_add_after</h3> <pre><code>/** * @param Varien_Event_Observer $observer */ public function applyDiscount(Varien_Event_Observer $observer) { /* @var $item Mage_Sales_Model_Quote_Item */ $item = $observer->getQuoteItem(); if ($item->getParentItem()) { $item = $item->getParentItem(); } // Discounted 25% off $percentDiscount = 0.25; // This makes sure the discount isn't applied over and over when refreshing $specialPrice = $item->getOriginalPrice() - ($item->getOriginalPrice() * $percentDiscount); // Make sure we don't have a negative if ($specialPrice > 0) { $item->setCustomPrice($specialPrice); $item->setOriginalCustomPrice($specialPrice); $item->getProduct()->setIsSuperMode(true); } } </code></pre> <h3>Event: checkout_cart_update_items_after</h3> <pre><code>/** * @param Varien_Event_Observer $observer */ public function applyDiscounts(Varien_Event_Observer $observer) { foreach ($observer->getCart()->getQuote()->getAllVisibleItems() as $item /* @var $item Mage_Sales_Model_Quote_Item */) { if ($item->getParentItem()) { $item = $item->getParentItem(); } // Discounted 25% off $percentDiscount = 0.25; // This makes sure the discount isn't applied over and over when refreshing $specialPrice = $item->getOriginalPrice() - ($item->getOriginalPrice() * $percentDiscount); // Make sure we don't have a negative if ($specialPrice > 0) { $item->setCustomPrice($specialPrice); $item->setOriginalCustomPrice($specialPrice); $item->getProduct()->setIsSuperMode(true); } } } </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
