Hi all.
We're about to start our 4th adventure in DH, and the players have got some money on their hands. We're also having some downtime between adventures. The assumption is that they stick to their "day jobs" during this time.
Of course the players want to treat IH and the core rulebook as big shopping lists and pick off cool items regardless of availability. I've let them buy anything more common than Scarce (not including) without any fuss. The last downtime period they were allowed one availability roll per week. Now and last time they're in Sibellus Hive, and I can't make the argument that the stuff doesn't exist.
How to you handle / restrict purchases "out of scenario" ?
