Hello Gustavo. If you want to promote ECA program,you must explain your potencionaly PRM that online store is future. There is so much stuff you can buy online,so why not to earn on that? You can find much products cheep on internet on wich you can put bigger price.Or they can sell stuff from his own house,they don't need anymore. If they don't want ECA,they can sell stuff thru members listing. Good luck and have a nice day.
