i got this about 13 years ago and this is a great way to collect the best grand funk albums in one box, since i suspect this is oop now what you get with this box is the first 4 grand funk titles, there are 8 more and they where released back in 2002/2003 at 4 titles a clip so once you bought this box with the first 4 titles you got a voucher and if you asked the next 4 upon release where available within a month and the last 4 in about 6 weeks after that so make sure you find a copy with all 12 titles as i think that would make it easier............ nice set this is
