Defined in:
app/services/spree/bank_payments/apply_discount.rb

Overview

Called for every payment (see PaymentDecorator), not just bank transfer ones, so switching away from bank transfer removes the discount rather than leaving it behind -- unless money has already arrived via a completed bank-transfer payment, in which case removal is skipped (see settled_by_bank_transfer?).

  # card payment, etc.) must not strip the discount: that would raise
  # order.total above what was actually collected and flip an
  # already-paid order back to balance_due.
