Yes, you have purchased products that come with full master resell rights. You are free to sell them on eBay, or any other website, or even by email if you so choose. Some products have limitations as to minimum pricing, and package selling, these products will state their proceedures within the zip file of that product or product package.
Note: If you purchased a storefront loaded with products, the storefront itself is NOT for resale, nor is it transferrable to another domain.
