A pre-ticked box is advice with the author removed. Reading it as a recommendation is not a mistake, it is accurate.
The count of digits is processed faster than the exchange rate. A larger nominal figure feels expensive and a smaller one feels cheap, whatever it converts to.

Digit count is read before exchange rate. The conversion then corrects an impression that has already been filed.

The second confirmation certifies nothing about the decision. It certifies that a decision was taken, to someone who will ask later.

Nobody has to intend an obstruction. Optimise retention for long enough and the process will discover it on your behalf.

Silence is not the absence of a claim. Buyers read an omitted number as the worst plausible one, and that reading is rational.

A step in a flow is an exit and a review point at once. Removing it raises completion and removes the moment the total was checked.
