I need a price comparison script with the same functionalities as the one offered here [login to view URL] This script should be integrated as a component in joomla 1.0.13 stable and should be easy to upgrade in due time. It must also include all the add ons listed such as: -Product catalog (including featured products) -Product comparison -Product rating and review -Price comparison -Merchant rating and review -Product search -Recent searches -Multi language support -Multi currency support -Search engine friendly pages -Price Alerts for visitors -Email a friend feature -Clickthrough tracking and reporting -Automatic thumbnail generation using GD or imagemagick -Auto-Crawler, for crawling merchants' websites to get products and prices (It is useful if a particular merchant dont support datafeeds) -DataFeeed Import, for importing products from any affiliate datafeed and automatically creating products -Merchant Area for merchants to manage their product prices, view clickthrough reports, update their profile and company logo -Administrator Area for administrator to manage every feature of site I'm not purchasing the script directly from Kaon is because the script is encoded. Your script must be well coded with suitable commenting so that any future maintenance or enhancement can be easily done.
