Helping my wife sell Microsoft Arc Mouse at half the price

My wife was very excited for a poppy red color and hence we bought this expensive mouse few months ago. Now the excitement for the color has worn off and for that reason I'm helping her sell at half the price in Mumbai. MRP - 8299 selling it for 50% off. Not sure if this is the right place to post this, if not, please suggest where could I post this. Thanks! Upvote for my husband duties ;-)
