skipflashboom Posted February 1, 2013 Share Posted February 1, 2013 When I first looked online to buy Perc I got the "If you buy this we'll report you the FEDs" scare. After I bought their multi color star making kit (which includes Potassium Perchlorate) they have no problems at all selling it to me. I do, however, buy my alum powder from another source.
