I'm in a tight schedule when I hobby, so longer dates don't benefit me. A special to me would be either a reduced price for an expected session, or an upgrade in services for the posted price or price I'm used to paying.
I can understand the rationale for new-client specials, just as I can understand why I pay more for Dish than new customers. But, whether she knows it or not, every provider has a risk premium factored into her pricing, and I do think that once a guy has demonstrated that he's no physical, financial, or legal risk, whether you call it a frequent-flyer discount or repeat-client reward, or something else, he shouldn't have to pay the risk premium.
