Two good book deals going on right now:
Weekly Reader has a deal where you purchase 10 hardcover classics and you get four "free" hardcover books for $20. Shipping is $3.95, and you can use code 125553 for 10% off. That equals 14 hardcover books for $21.95, or $1.57 per book. A caveat: there's no way to know what books you will get. However, I am thrilled with what I got and after checking Amazon I found that all of these books retail for $10+ each. The books in this deal are all pictured except for Green Eggs and Ham. Note: on the order page, make sure you say 'no' when asked whether or not you want the unsecure items displayed. This will make the little lock appear that tells you you're on a secure site.
Also, are you aware of the Aquafresh Dr. Seuss book offer? Buy any combination of Aquafresh Dr. Seuss toothpaste or toothbrushes and get a FREE Dr. Seuss book by mail. I bought two toothpastes when they were on sale for .99 at Walgreens and I had a coupon. The toothpastes themselves went into my Operation Christmas Child shoeboxes. All I had to do was cut off the UPC labels, fill out this form, and I got Green Eggs and Ham by mail in about a month.
Want smart kids/nephews/nieces/grandchildren? READ TO THEM! That's why my head is so huge, y'all. To hold all my brains.
