If you are still looking for copies of Twilight, New Moon, Eclipse, or Breaking Dawn, you are in luck! Both Barnes & Noble and Borders are running coupons right now to take a percentage off any one item on their websites, which includes the Twilight books and Twilight Soundtrack.
The Barnes & Noble coupon is for 10% off any one item and is available through December 18. You can click here or use coupon code D9E4E3T.
Borders is running a coupon that will let you take 30% off of any one item and it is available through December 24. You can click here or use coupon code BAC1226X. Another great thing about Borders it that your shipping is free with a $25 purchase or you can have anything shipped for free to your closest store.
Of course, these coupons can be used for items other than Twilight books, but they do have all of the Twilight books in stock at pretty good prices as well as some of the special Twilight books such as the Twilight Movie Companion. And you can get them in time for Christmas to give as gifts.
