Any one use mother earth coco pearlite mix?

I tryed all the stores around and no coco.. Looks like I'll be ordering from the internet... Is there a good coco pearlite mix. I found peatmoss and pearlite. I'd rather buy a blend then buy all the ingredients n mix em.. Unless all I need is coco and pearl. I considered the bricks but not to sure I'd make mix right any in put will be appreciated
