dont know why galaxy is charging so high.. maybe they havent updated their site for this product.. you should call them for accurate price and availability.. they usually have much lower rates/. also they are reliable,, and they have a physical shop where you can check first hand what you are buying and take back product if problem.
Dont know about symbios..
Shophive and Vmart are good reputed online stores..
Thanks for the response Farhan.
