Only way you can get them is if someone else who purchased them uploads them online for regular download. Once the site closed, that was it when it comes to being able to purchase them. This is always a possibility whenever a producer decides to hang em up. Sometimes they decide to scrap their entire site and all of the clips posted there. Like when Shy&WildTickling called it quits and announced his site was being taken down, a lot of people purchased clips before they were gone for good.
I get that in some cases when producers move on they have to scrap all of their fetish work, because they don't want it coming back and affecting whatever they decide to do next. But it's kinda unfair to those who either couldn't afford clips at the time, or got into tickling at a later date. They're really just shit outta luck.
