With prices locally, (even during normal times) I will be making a bulk order periodically. Between smokeless, black powder and primers, I can make it worthwhile pretty easy.
It really doesn't take much to start saving vs local prices. Especially my black powder. It's a bit of a pain for the shops to store and deal with so they charge a premium. Most around $30 a pound. I wanna say I paid $17 or something a pound. So I save over 10$ a pound on it.
