Why does it seem that some girls show up much more often as a special offer? For example, Maggie seems to be featured 3 or 4 times every week and Ting isn't far behind but haven't seen Alexandra or Vicky S (just to name a couple) in forever. Are they trying to push less popular cards? The mix defies statistical probability if it is truly supposed to be a random selection.

I agree.

Well....Duh! Of course Totem will try to maximise purchases of each card, and that means pushing those with fewer sales.

Don't be dissuaded from buying cards with low scores. Some of my favourites have scores below 8. I set the Erotic Level in Desktop Settings to random hotness, enable only clips with topless or more nudity, sit back and enjoy. Totem doesn't film unattractive girls.
