以下是您的快速解决方案.

Here is quick solution for you.

您可以使用产品的费用"字段来定义零售价高于您的价格的百分比.默认情况下，费用"字段用作您为产品付款的金额的备忘，并且在前端的任何地方都不会使用.

You can use a 'cost' field of the product to define the percentage by which the retail price is higher then your price. By default 'cost' field is used as a memo of how much you paid for the product and is not used anywhere at the front-end.

然后转到主题的template/template/catalog/product/view/tierprices.phtml，并在$_product = $this->getProduct();行之后添加以下行:

Then go to templates/template/catalog/product/view/tierprices.phtml of your theme and add the following lines after $_product = $this->getProduct(); line:

$multiplier = $_product->getData('cost');
$multiplier = $multiplier ? $multiplier : 1;

以及<?php endif; ?>和<?php if (!$this->getInGrouped()): ?>之间的以下行:

Retail price: <?php echo $_coreHelper->currency($_price['price']*$multiplier, true, false) ?>

我确信您将能够根据需要设置样式.如果有不清楚的地方，请告诉我.
