I sometime buy scenes from adultempire.com especially scenes from websites which charge extra for downloads. They usually have sales like 40%, 45%, 50%. Usually when they have these sales there might be a few which "opt out" and those are a full price. However, the last couple of sales including the current one, many are at the advertised percentage and others are at a different percentage. It is even the case with the percentage is different for two movies from the same studio where the older one has a lower percentage discount.

Any thoughts?
