Most people wouldn't store flash. It is way too sensitive. Most make what they need the instant they need it. You can store flash but you need a Type 2 magazine, which has to be bullet resistant, basically same kind of magazines used to store HE.
Even commercial flash powder that you can buy comes in 2 bottles, you mix what you need right when you need it.
The issue with bp is that since it's an explosive, if you use it for anything other than sporting use, then the ATF could require you to have a permit for it. Furthermore since bp is an explosive, the store who carries it would require extensive licensing and storage, so most places aren't going to have it especially when black powder substitutes do not have nearly the same storage requirement that bp have. It is not hard to make them yourself but if you transport it without a license, it's illegal. I should probably check with pyros on how they get around that (taking their own shells to PGI conventions for example). However I am not sure if RSO's will allow homemade bp as ejection charge on their range.
You could make the bp you need right when you need it (at the launch site, though I suspect the RSO will not allow it), however since bp requires a lot of preparation and granulation (though in practice you just need a few grams per flight anyways... you could make it with a mortar and pestle if you are patient). Also making bp takes skill and luck... then you have to wait hours for the bp to dry once you granulate it.
I don't know how it works legally with reload kits including black powders in its ejection charge however... Maybe it has to do with EX certification that those motors have to have??
