So there is a lot of good information on their FAQ page about the collective.
Q: What if I need three or more Star Trek: Attack Wing- The Collective Organized Play kits to support my store’s monthly Star Trek Attack Wing- The Collective events?
A: Talk to your Sales Rep; every request for additional kits will be reviewed on a case-by-case basis.
So a store can order up to 3 kits per month (with 1 brick per kit as mentioned in other places), but it's going to depend on the store's past performance, etc.
This is where you can view the FAQ about The Collective.
On the brick:
Each ship pack contains options for generic/named ship, captains and upgrades that can provide multiple different configurations for a 30 point ship.
