Is there a limit to the amount you can ship before they charge hazmat? I was going to order from Mid South but when I placed a 1k bulk pack in the cart there was a $26 hazmat fee added. But when I placed 1k rnds in 20 rnd packs there is no hazmat fee. I don't do a lot of business with Mid South and am wondering if this is their way of putting something on sale and making back the price somewhere else.
