Well myself I'm really picky, and so I don't buy from most of the producers, but I do prefer clips4sale over a recurring monthly fee. I have however subscribed to sites in the past and just got what I wanted from them and then cancelled my membership.
Just today I noticed that clips4sale has updated it's look twice in 2 months. The first change was a great move in that they made it so that only stores with tickling would come up and if you opened one of those stores it would have it preset to just show that stores tickling clips. But this 2nd change I think was a bad move, so that could explain any recent problems producers would have with making money. The site just seems clumsy unless I'm mistaken, but I see that they've now arranged it so that it's by only the recently updated, which by the look of the list that comes up I suspect is not a full list if you haven't looked for the last 3 days. Not to mention that the part below that shows new studios, which isn't correct. Not only that but if you mouse over the new stores it doesn't give an accurate last updated date. So basically unless clips4sale is planning on updating this new system so it's better, clips4sale just basically fucked their own site up.
