Magento doesn't displays group price

Question

This is a bit frustrating but, some of my products displays the group price while some others not.

I have the customer group X, and for this customer group I have different prices than the regular price. The issue is, that I've configured all the prices of 'group price' in all the products but only some of them displays the group price on the frontend. Anyone knows why ? Or some clue to find out why this can happen ?

When I try to see the prices, I access to the website with an account of a customer from the group X, so this is not the problem.. but I don't know where the problem is.

Thanks.

EDIT: If the regular price is higher than the 'group price' magento displays the group price, but if the regular price is lower than the 'group price' it doesn't display the group price... this is very strange, isn't it? Anyone knows why?

Answer 1

This is actually by design.

Magento will show the minimum price, because the retail price should always be higher then the group prices (otherwise, why wouldn't the customer just not login then attempt to checkout).

This is evident in the following function:

    /**
 * Apply group price for product
 *
 * @param Mage_Catalog_Model_Product $product
 * @param float $finalPrice
 * @return float
 */
protected function _applyGroupPrice($product, $finalPrice)
{
    $groupPrice = $product->getGroupPrice();
    if (is_numeric($groupPrice)) {
        $finalPrice = min($finalPrice, $groupPrice);
    }
    return $finalPrice;
}

Source: app/code/core/Mage/Catalog/Model/Product/Type/Price.php

So running through you scenario above, using EE 1.13, I logged into a customer account. The regular price of the product was $150. The retailer group price I set as $250, and the wholesale group price I set as $125. The wholesale displayed as $125, however the retailer group price was $150. Again, this is as design, it's not a bug but a feature.

You can also try the logic by trying to add a "special price" that is greater then the regular price. The special price won't show.

Solutions for your needs.

1. Make sure your regular price is always higher then groups
2. Possibly create an extension that extends the logic in app/code/core/Mage/Catalog/Model/Product/Type/Price.php (this may not be the only file you need to extend, however it is the file with the majority of the pricing logic).

If you do end up creating your own extension, always remember to never edit core code.
