IMO the discount needs to be a high percentage. The higher the better. That way the big mega stores and discounters like Walmart, Kohl’s etc. won’t be able to opt out of it with their phony inflation of prices and then 30-40% discounts which after their “discounts” are only 5 or maybe 10% less than every place else. You’ll have price differences of course, but competition will still apply, especially if you discount everything sufficiently. If its at or right after retail sale no economic agent consumer or business is harmed by it because business is guaranteed their best price despite the rebate and the economic process has transformed itself from production to consumption. And of course the real point is to increase consumer demand and eventually downsize any necessity for consumer finance….even for big ticket items. The discount is a powerful means of implementing Grace as in Gifting as a new paradigm integrated into the economy and so ending Finance’s domineering and manipulative hold on everyone and all businesses.
It’s a no-brainer.
