Amazon.com has a huge sale on select DVDS, including Smallville and Supernatural season sets. SV are around $24.00 each season, and I think Supernatural was $34.00 each. They have a bunch of other tv sets on sale too.
I noticed a lot of people are doing a book reading meme. A few years ago, I joined an online book club that I've really liked. It's at www.zooba.com. They have a very good selection of books and are constantly updating with new releases. This is a brief explanation of how it works from the website (right now, the fee is $9.95 per month + sales tax):
Zooba charges a recurring membership fee, which includes one book per month and no additional charge for shipping and handling. Plus, with the "Buy now" feature, you can always buy additional books at the same low, flat price with free shipping. Don't let your membership go to waste: keep your Reading List full of books to ensure you'll always receive your regular book shipment.
