Steering Wheel Guide - Logitech Driving Force GT

Dear All,
I want to buy Steering Wheel - Logitech Driving Force GT.
But confusion is, I have got big price variation for this product in different online websites.
Shophive:
Price: 18,099/-

Galaxy:
Price: 20,500/-

Vmart:
Price: PKR 17,800/-

Symbios:
Price: PKR 14,009/-
Ref: http://www.symbios.pk/logitech-driving-force-gt-940-000021-pakistan.html
Pertaining to above mentioned references, why there is so much big difference.
Can anyone guide me for this.
Thanks!

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.
