Just after another thread that had the suggestion - I made a rounder upper that does 2/3/4/5x the change amount, and then keeps the total amount Round.
That’s seemingly more what people wanted with Advanced round ups -
So, for example. If you have the 4x - you spend £1.90.
Your round up would be £0.10 * 4 = £0.40. To keep the transaction feed ‘round’ that rounds to £1.10 so your total amount = £3.
I’m also all ears if anyone has a better way of describing this? Spare Change Multiplier Round Up?
