I ordered a book for TBD once, it took about 2-3 weeks for it to arrive. & if your order get's lost/doesn't arrive they will give you a full refund or send you another copy.

& it is sent by air mail. No worries if you're not at home, cause the posman will just leave it in your letter box, no signature required.

My conclusion is TBD is a very trustable online book store. My order took a week longer than it was supposed to arrive so i sent them an email about it and they sent me another copy, so in the end i received two copies for the price of one.
