I got these online for a really great price; it pays to shop around and wait for a deal. I've seen them @ Sam's Club online as well. I've seen them as low as $7-$12. Ikea came out with a similar concept and is actually better. Tykelight is hard plastic; Ikea's version is soft silicone material; the downside to Ikea's is that it only comes in 3 colors - red, green, and blue, and the shape is different according to the color. II find that the battery lasts just as long and it's also rechargeable; Ikea's is the cheaper alternative, plus if she drops it, I don't worry about it breaking.
