@TeamFlordia@CryptoHitmann @Conservative1AZ In the UK the coupon would generally specify that the reduction was on the newly marked price (or the original depending on intention).
@Joel_Garcia_2@CryptoHitmann@MegaMachina @Conservative1AZ 300% increase, as the item is now only 25% of the original price meaning it needs to increase by three times this amount to recover the discount.
