I have used several different Wordpress eCommerce plugins. All have their issues. I decided to use MarketPress for my current project, as the WPMU dev is a well respected community.
I will start off by saying I LOVE that everything uses the Wordpress core. Custom post types, post meta, etc. All very good.
However, I am finding a lot of limitations. First of all. Where is the documentation. I'm not referring to the page which shows you how to install and setup the plugin. I'm talking about the documentation for hooks and filters, theming and customization options etc. I am finding nothing on the website. The template-functions.php file is hardly helpful, aside from the fact that it is missing several functions that other plugins have.
I want to style my cart, and edit the item name in the cart, yet I can't seem to do this. There is no function to pull the order total? What is the point of creating my own templates for use with MarketPress if I can't even custom the cart table.
I would love to give this plugin a shot, and use it for all eCommerce sites, but without key features that give me FULL control over my site, I can't do that. I thought Shopp Plugin was extremely buggy, but it got the job done and allowed me to do whatever I needed look and feel wise.
Somebody tell me I am wrong and that everything I need is just a few clicks away.
