It's a Scientific Experiment. Really.
Purely for experimental purposes, and not because I needed or wanted any books (perish the thought!), when The Book Depository opened up their American site, I decided to give them a try.

I ordered four books on July 28, all of which were discounted to be a smidge cheaper than Amazon, and the order had free shipping. Three of the books arrived today -- in three separate packages. Clearly they're getting a great deal on their shipping!! So that's eleven days from order to arrival, a little slower than Amazon Super-saver shipping for me, but not by much.

I'm also wryly amused that the book which isn't here yet is the book about Islam. (The Muslim Next Door, if you're curious.) If I were prone to conspiracy theories, I'd be saying "See? See?", but I figure it just got separated in the shipment and will probably arrive Monday.

Anyway, if you aren't in a hurry for your books, want free shipping, and don't want to use Amazon.com, The Book Depository is a decent option. Assuming my fourth book actually arrives next week, I'll likely use them again.
