The problem is shipping them. Much easier to sell locally. Have to have all the hazmat certification and such to ship them I believe.
When my wife bought that sleeve of 100 LR primers a while back... $40/100 (I choked when I found out)... they showed up wrapped in newspaper in a manila envelope.
I had a brief moment where I considered reporting the guy to USPS... Out of retaliation for highway robbery I suppose... But I got over it and instructed my wife not to buy anymore.
I'm sure the postmaster would probably have a coronary if he/she found out how many primers are being shipped incognito right now. Lol
