I would like to design a webshop in Photoshop. I want to be as free as possible in designing the look and feel of the shop, without having restrictions of the chosen Ecommerce plugin!!! After the design is finished, I want to convert the PSD to a Wordpress theme. Which Ecommerce plugin is very very (!!!) customizable, so I am free to design how I want it, without being restricted to the templates of the plugin (or the way the plugin is setup)? I heard WP Commerce is most used, but not that customisable designwise. Is Shopp, Eshop or PhPurchase a better option? Do they all have the option to change the CSS? I hope to see some good advise.... Thanks!
