I just received my battery grip in the mail yesterday and it DID NOT come with any battery packs. Just the grip and two battery tray inserts - one that holds two Canon rechargable batteries (not included) and one to hold 6 AA batteries. I also had the expectations that a battery pack or two would be included, but since they sell for about $50 each, in hindsight that seems like an unrealistic expectation. But this battery grip is worth the $140 I paid and will accommodate the two Canon batteries I have (one that came with the camera and one I bought separately). I bought this grip because I'm a guy with larger hands. Before you buy this grip, I would recommend you first use the battery that came in your camera to see how long it lasts and then buy a spare (and pre-charged) charged battery (or a half dozen AA alkalines) to keep in your pocket/camera bag in case you need to change during a shooting event.
