Ski Salopettes Best Way To Sell Unwanted Ski Jacket/salopettes?

Best way to sell unwanted ski jacket/salopettes? - ski salopettes

My brother went skiing a few years ago and soon Im going in 1 month. My parents want me to coat / overalls mens mens'm use only with small, so he would not let me go skiing to be agreed resold. EBay is the best way, or should I them to a camp mindi (where only a month to sell to get money and buy a new jacket and overalls).
Thanks
