I am used to working on Wordpress... I am going through great themes I want for my web store but my head is about to explode. Some of them are "Magento", some of them are "OpenCart" it's just all so confusing. I legitimately don't even know where to begin. I want to set up a web store selling niche products with a cart and checkout, that redirects users to their country's Amazon for purchase I want to use these awesome themes for my site. Everything is ready, the site content, the keywords, all I need now is to set up the actual webstore. Please help me.
