The Mystery of bookdepository.com Prices
I frequently buy books from bookdepository.com. Book Depository is reasonably fast (most purchases arrive within a week), offers free shipping to pretty nearly anywhere, and features prices that are often better than Amazon. (Book Depository ships from the UK, but books are exempt from customs in the US. Unlike Amazon, they do not collect sales tax.)
However, getting the best price on Book Depository is a bit of an art. From the US, Book Depository hasat least two web sites: bookdepository.com and bookdepository.co.uk. (The latter URL will redirect you to the .com site at first. But the second time in the row ones goes to that URL, it will send you to bookdepository.co.uk .) The .com and .co.uk web sites feature significantly different prices on many books. I wish I could tell you that one web site was consistently cheaper than the other, but I have found no significant pattern.
Interestingly, I get a third set of prices when connecting through a UK proxy. Book Depository from the UK makes it easy to get pricing in $US (simply slide down the currency selection in the upper right hand corner, and pay with Paypal, for example), and the prices are often even cheaper than bookdepository.co.uk or bookdepository.com from a US IP address. Also, it turns out that many books that are listed as “unavailable” from the US web site are easily available from the UK web site.
Especially when purchasing books that are only available in UK editions or scholarly books, the pricing at Book Depository is often very attractive. I’ve generally had good service from them.
