BEWARE: Promo codes for Book Depository at various coupon sharing websites, but nowhere to use the on BD order form. I placed order then contacted their help desk on how to apply discount. Very inflexible Amber-Jade replied codes not valid unless emailed to customers directly. Poor business model when most other companies place promo code box before invoice total is calculated. Misleading to buyers who consult coupon sites. No conciliatory offer whatsoever. Will not buy there again.
