If you’d like to display products of your online store in a grid view and you’re using WP eCommerce, the free WordPress e-commerce plugin, then you’ll need to use a paid add-on called Gold Cart. In this tutorial, I’ll show you how to implement a CSS-only grid for the products page of your WP eCommerce-powered store.
You won’t have all the features of the Gold Cart add-on, nor the ability to configure the products grid from the WordPress admin panel. However, the products display is clean and not too hard to achieve, if you have some familiarity with CSS.
