Solving a problem is often about finding the right approach / fudging the problem into something you can solve. And there is actually a disruptive solution to this: online shopping. Amazon has cheese cloth.
So that we don't have to wait for them, we're trying to enable crowd-sourcing as well; "I saw OBSCUREITEM here in case you're looking for it in town".
Again, very aware this is only your problem at the store's front door, but maybe it's nice to know someone's working on it? :)
