> Would you be interested in being a beta user when it’s ready?

Yes but no.

Interested but a lousy beta tester - I'm in a tiny rural town with a single community owned shop .. I'm exposed to Big Four shops maybe once a quarter or so.

Regular items we get in massive sacks from primary producers, quarter sheep to freezer, etc.

I reckon you'd get enough bites from reddit r/Australia .. even from the smaller state sub reddits if you want small scale constrained local area testing and building out from a base.
