  1.  @Condor4R  Anything over 35% concentration needs DHS approvals, because over 35% is used for rocket fuel. This is according to my supplier, Hawkins Water Treatment Group. We use hydrogen peroxide in our water treatment plant and I asked about getting higher concentration and just using less, so we wouldn't have to move 55g drums, and that was the answer we got. The commenter above is pretty close we pay about $750/drum delivered.

  2. This is misleading... You go to pre-order a foldscope and the shipping alone is a dollar, and a single scope is $25! That's a 5000% markup over the fifty cents mentioned in this video.
