What are the differences between the basic (free) and premium membership for vendors?
It is free to become a member/register as a vendor and create your store. There are no fees to list your products.
RD2RD charges a service fee each time a product is sold. Basic (free) members pay 35% service fee. Premium members pay 20%.
Stated another way, with a premium membership, your earnings are 80% of each sale (for basic memberships, earnings are 65%). A premium membership is optional, and is $49/year.
