Newfoundlander: where can i learn ninjutsu for free? where can i find flash powder and salt peter as well?

ya the title asks it all so post and thx ^^|||Are you planning on making smoke bombs with salt peter? I bought some on eBay, but the shipping costs are generally very high. Some butchers stock it (used for smoking meat or something I think), as-well as garden stores (used for killing roots or something like that). If not some tomato or strawberry fertilizers contain a very high percent of it, and smoke bombs work fine with that too.
