Resell rights are similar to Private Label with a critical difference or two: You are not allowed to make any changes to the content, and you are not allowed to claim the work as your own. Instead, you purchase resell rights to a ready made product, and this allows you to sell the product as if it were your own.
Unlike affiliate programs, you do not have to share part of the sales proceeds when you sell resell rights products. You do have the merchant related responsibilities however. Since you are selling the product directly, you are responsible for delivering it, dealing with refunds or customer support, and so on.
