Of course, the biggest reasons why I love the beginning of the month is that there is almost always a swarm of free ebooks. Several publishers offer a new batch of free ebooks every month. You can find these freebies listed on several sites, but here are my favorites
The Free NOOKBook thread on the B&N forum
Books on the Knob
I just downloaded a bunch of freebies this morning. A few are from Sourcebooks, a publisher that only tends to make their freebies available for a couple of days, so don't wait to check out the new offerings!
