Accumulate a "credit" of a monetary amount per case ordered. Allow applying as a future discount and manually adjusting amount

Thanks for the suggestion, Tom.

How would Breww know their progress towards a bar tab?

Is One frees - cumulative retros/loyalty discount/scheme (e.g. get one free for every 10 purchased) the sort of thing you’re looking for? If so, you should make sure to vote for that other thread as this one would be blocked behind that (step 1: implement retros, step 2: show their progress on the trade store).

Cheers
