I hope someone can help me with this, I am trying to extract the product prices from magento based on customer group.
I am not using tier pricing, I simply have a product with a standard price and I have specified different prices for each customer group. For some reason I have been unable to extract this information.
I can see that the price mappings seems to be held in the table 'catalog_product_index_group_price' so I guess I could write direct SQL to extract these but I would much rather use the PHP Mage model to do this, or the V2 SOAP API.
I have tried many methods, currently im using something like below, but without success the price variable is always empty.
$rules = Mage::getResourceModel('catalogrule/rule');
$price = $rules->getRulePrice($now, $websiteId, $customer_group_id, $productID);
