I have a osCommerce based store running and need the following revamped (convenience wise for customers). Product listing - It's currently the stock oScommerce (different colors though). But I want it redesigned/recoded so it's image and right under it will be the model number, product name. Then to the right of the product name, it will be the price, quantity, add to cart button. Would also like to have a "Details" button, which would redirect it to the individual product with description, etc. My Cart - Needs to show unit price, Need this reorganized in a more convenient way. I currently have it that automatically refreshes your page if you remove or change quantities (I need this removed so that customers need to click update manually). Also would like to have an "estimate shipping Also, need to redesign the boxes used in oScommerce. (some boxes with same design/look) - This is relatively very simple.
