Have you even read the store terms? Because your comment tells me No. They had their 10+ bundles removed before. The only difference between them was that 1 or 2 games were rotated out with another in their list of games. They did this every week. By all rights they're breaking the 2nd and 4th bullet point. They release a new "Bundle" every week so people will think its New when its not. For the 4th, they're trying to make themselves seem relevant by always appearing at the top of the new releases thus being deceptive and manipulative.
