Where are you located ? The reason behind the 50 bucks is am sharing the shipping cost 50% with you as it might just cost me more than 100 bucks to your area via DTDC. DTDC is more secure and safe and their shipping costs depend upon the weight of the item, hence the 50 bucks extra.
I have a Wireless Controller which I purchased few months back and just used for 1 month because My Xbox got hardware problem and i sold all part of it just controller left. Due to lot of work pressure these days i am not able to list it. But if you want to see some pictures let me know i will post it. Controller is look like very new.
