I don't use LRP's so I haven't been looking. When I was hunting primers I would just check Midway, Brownells, Powder Valley, Academy Sports, Etc. a few times every day. They do show up, but in small quantities that go fast. I was able to by some cases of 5,000 that help offset the hazmat fees & most limit you to one or two bricks. Locally Scheels had primers when I was there last week & even though I didn't need them I bought a brick of Magnum SPP at $80 & added it to the stash.
