Amazon Book Coupon extended again ($5 off $15+)

If you haven’t used this yet, the Amazon Books coupon code GIFTBOOK that gets you $5 off purchase of $15+ in printed books at Amazon by Amazon itself has been extended again, it ends on Saturday 12/17/16 at 3am eastern, unless it gets extended again.

PS: it also works with some calendars, depending on how they are coded in their system, so if you want to buy photo calendars, or if you sell your own photo-calendars there, you can test the coupon on them and tell your friends to buy them with the extra discount 🙂
