i started my website befor 10 days. https://satis.aluminyumcuyuz.com
in this website, thanks to prestashop, i can sell products. but i want to put second hand product page for my customer and they can sell their products also here. When they enter as a customer, they can buy my products, but also they should put their second hand products and sell them. i enabled b2b mode. but what is next, i have to do?
could you please advise how i can do this.
thanks for your kind attention.
