Amazon once again takes $5 off book orders of $15 of more via coupon code "GIFTBOOK". Plus, Prime members net free shipping. (Non-members can spend $25 or more on books or $49 overall to qualify for free shipping; otherwise, shipping starts around $4.) Although not as good as the $10 off $25 we saw on Cyber Monday, it's still the second best book coupon we've seen at Amazon this year. It's limited to one use per customer and applies to print books only. Deal ends December 12.
