I did some research on hikashop, after looking into many other carts. I installed on joomla 2.5.2 and it took me some time to get comfortable working with it. It's not complicated but I'm not an expert in eCommerce. However after getting to know how it works its the easiest module you can ever imagine. Add to that they have great documentation where you can find most if not all the answers you need. Also I had an issue with FedEx plugin which is not developed by Hika, however Hika support went the extra mile to help me on that problem which have nothing to do with their module. The least I can say is that Hikshop is great, and the support team is amazing, they take ownership of their issues and their response is almost immediate. Especially Nicolas he's amazing. I would definitely recommend HikaShop and I will give it FIVE *****. Keep up the good work.
