Magento Certified Developer GuideCategory: 7. CatalogWhat is the priority of the different prices that can be specified for products (price, special price, group price, tier price, etc.)
Manish Prakash Staff asked 5 years ago

These is not priority as such, its simply the minimum of these prices.

public function getBasePrice($product, $qty = null)
    {
        $price = (float)$product->getPrice();
        return min($this->_applyGroupPrice($product, $price), $this->_applyTierPrice($product, $qty, $price),
            $this->_applySpecialPrice($product, $price)
        );
    }
