I don’t think the merchant would pass on the savings to a customer. Mostly because it’s a tiny amount (2%) for the customer but that’s a huge amount across all transactions for the merchant.

So the incentive would already be there for the seller to accept bitcoin like what Steak ‘n Shake has done.

And I believe most Bitcoiners want to support the circular economy more than save 1-2% on a transaction so we are aligned as well.
