Magento: Get product price given a customer group

Question

On magento 1.7 I created a promotional price rule of 20% discount for "special members" customer group.

I'd like to display both prices. I thought there would be something like

$_product->getPriceByCustomerGroup( $groupId );

Goal

(not logged in):

• Regular price: $10.99
• Member price: $5.99

(member logged in):

• Regular price: $10.99
• Member price: $5.99

Answer 1

Fished my own wish after hacking on it for a while

$now = Mage::getSingleton('core/date')->timestamp( time() );
$websiteId = Mage::app()->getStore()->getWebsiteId();
$customerGroup = 4;

Mage::getResourceModel('catalogrule/rule')->getRulePrice( $now, $websiteId, $customerGroup, $_productId);
