这个需要我们自己添加一个block块供我们调用，可参考new products的block类，建立文件app/code/core/Mage/Catalog/Block/Product/Special.php

复制app/design/frontend/base/default/template/catalog/product/new.phtml到app/design/frontend/theme/default/template/catalog/product/special.phtml，修改为相应标题和产品显示数量
在后台首页的CMS Page模块添加调用代码：

当然要想显示特价产品，在产品管理处还是要设置的，进入产品管理的Prices栏，Special Price和Special Price From Date都要设置，那么前台就会显示特价产品。
