Would you like to ignore the indexed product price in the templates (for example in catalog/product/list.phtml where the indexed price is used)?
Then go to: catalog/product/list.phtml
load($_product->getId()); ?> getPriceHtml($product) ?>
There are two occurrences in list.phtml, so don’t forget to replace it twice. Only do this when it’s the only solution of displaying right prices, since loading the product takes extra time, compared to loading the indexed product price.
