    >>> invoice_line_w_discount.amount
    Decimal('8.80')
    >>> purchase_line_wo_discount.reload()
    >>> invoice_line_wo_discount, = purchase_line_wo_discount.invoice_lines
    >>> invoice_line_wo_discount.gross_unit_price
    Decimal('5.0000')

    Decimal('0')
    >>> invoice_line_wo_discount.amount
