Agreed. Actually, it'd cost more to order 3lb or less, but anything over 5lb is worth ordering. Since my crew typically goes through about 25lb/event we usually order it.
I'm planning to go to the Hernando shoot, though I don't have any projectiles for my cannon right now, so I'll just be a spectator. Should be a good time, and maybe I'll be able to take some pictures instead of shooting the whole time!
I wasn't sure where the breakover point is. I get it by the case myself, so it is a LOT less expensive that way. Not to mention I don't know of any in the area that carry the real deal.
Take pictures? Bet someone needs crew and you will be right there getting all smoky and dirty.
At reenactments I carry some cards with me, and when people ask me to pose, I give them a card and ask them to email the photo to me, pretty please, since I don't have the time to take photos, what with talking to the public, getting set for battles, cleaning up after, and cooking breakfast and dinner.
