Using the process outlined in our blog entry Integrating Wordpress into Zen Cart, we are able to make the experience between your Zen Cart store and Wordpress blog seamless to your customers by enabling Wordpress to display as a page within your Zen Cart store.
Once integrated, customers will still be able to see session-dependant information that may appear in the site-wide portions of your Zen Cart template. For example, if a customer adds products to their cart and you have an area in your header that shows a shopping cart contents, this session-dependant area will still be accessible on the blog page.
Currently, our service does not include integrating the logins between Zen Cart and Wordpress. This means your customers will still have to register on both your store and blog. If this is a feature that you need, please contact us for a customized quote.
