The repacking seems to depend on who imports the ammo and what vintage it is. I recently purchased some '90's vintage Czechicon ball from a dealer out east. From the factory it came packed 300 rounds to a plastic sleeve, 4 sleeves to a crate, with no tin liner. In each sleeve there are 30 individually wrapped 10 round chargers. The chargers come in a carboard sleeve and sealed in a plastic packet.

The cases I purchased were repacked in the Czech Republic and contained the 120 individually wrapped chargers with a bilingual ammo "data" sticker making them nanny-state approved for sale. They were not repacked into the 300 round bags.

A few of us went together and ordered 10 cases and got a discount. We got it for $220.50, tax and shipping included, delivered all the way across the country. That works out to $0.18375 a round. Not the lowest price you can find, but if I want to get it cheaper, I have to drive at least two hours. This stuff came right to my door.
