Didn't buy but four books today with store credit at McKay's, but I think the four I got each were worth the month (over $40 in store credit) spent:
Very curious about the Short Stories by Latin American Women: The Magic and the Real anthology, as it contains a mixture of women writers that I've read and enjoyed to varying degrees (Isabel Allende, Rosario Ferré, Elena Garro, Elena Poniatowska) with another 20 that I have not yet read. I was also very fortunate to get the Library of America volume #233, American Antislavery Writings, still in its shrinkwrap for only $20. Toying with the idea in the future of doing a series of essays on the Civil War era volumes that LoA has produced so far (might wait until spring 2014, after the release of the fourth volume of the Civil War series they are producing is released).
Finally, couldn't pass up two Loeb Library editions of Julius Caesar's The Gallic War and Cicero V: Brutus, Orator.
