Some distributors require a percentage of the sales - that percentage can vary widely from 30-70%, depending on the arrangement. Other distributors charge a flat fee. Still others will distribute a validated, well-formed EPUB file at no charge, because their core business is conversion or some other service. It's important to explore, determine exactly what you want, and see which service supplies that and for how much.
