I am not sure too. Final Fantasies 5, 6, 7 and 8 costs 10bucks? That doesn't look like a sale to me.
FFX/X-2 HD should cost 20 bucks even without sale. The 40 bucks they normally charge is way too expensive for old games, IMO.
Old games with upgraded graphics, 2-4 games in the bundle, trophy support, and (in SE's case) additional content that never made it to certain parts of the world is a damn good deal.
