I don't know of another program that offers the same affiliate support, to the point that the checks actually arrive early every two weeks. For instance my check for the period ending 4-30 was supposed to be paid out on 5-25, I got and cashed it on 5-17.
Adult Webmaster Empire has been around a long time, and is one of the few brands you can 100% trust in this industry. My checks get bigger and bigger every two weeks.
