I hardly buy new books these days, preferring the library and used book sales! However, with my new Kindle, I bought several eBooks in 2010, though nothing more than $2.99 each, and I've downloaded over 200 free classics.
So far in 2011, I've made the following purchase(s):
1. A Haunting Smile (Land of Smiles Trilogy) by Christopher G. Moore,
4. 9 Gold Bullets (Vincent Calvino Crime Novel) by Christopher G. Moore, eBook, $7.95.
UPDATE: I have just found there are free e-Book downloads at Many Books and at Project Gutenberg.
Thanks to Diane at Bibliophile by the Sea for the idea of keeping track of book buys/costs. I hope to shock myself by spending as little as possible! We'll see.....
