In case you're interested, Smashwords is having their giant book sale this month.
You'll find so many free and cheap e-books (in formats for whatever e-reader or regular computer reading you might want!) that you could stock up on enough books to get you all the way through to their winter sale!
My books are there, too, and for this special promo, they're all free! Check it out! Just use coupon code SFREE at checkout.
