I am working on a store that is using bundle/catalog/product/view/price.phtml instead of bundle/catalog/product/price.phtml. It is Magento v1.9.0.1. This is set in the core base XML as:-

<action method="addPriceBlockType"><type>bundle</type><block>bundle/catalog_product_price</block><template>bundle/catalog/product/view/price.phtml</template></action>

So, I am wondering if your tutorial contains a typo in the path to the price template for bundled products or if not (likely), what determines which price template is used? The contents of each are quite different.
