The Guardian - Run of Paper Display Advert (Black & White)

Standard run-of-paper display advert, black and white. Priced by size. Rates exclusive of VAT. NOTE TO DEV: series/volume discount applies (5-10 insertions +2.5%, 11-15 +5%, 16-20 +7.5%, 21+ +10% extra discount off list) but is a percentage-off-quantity structure, not a fixed price per periodDays, so it does not fit discountTiers as currently specified (price is an absolute amount, not a %). Left out of discountTiers pending your input on how to represent this - see chat for detail.
