Yea I had some weird stuff happen with mine as well. Originally they changed me for 10 mags, only 5 shipped, then a little bit later the other 5 shipped and I thought we were done. Then last week I got charged again and told 5 more were on the way. No big deal as I figured I'd either just keep them, or pass the deal onto someone else.

Bad thing is this mystery set of mags has never arrived.
