In the past, I have been a happy customer of Amazon USA for technical books, and more recently, even for fiction. Australian bookshops seem to have very limited and expensive stock, so buying online is an attractive option.
Recently some of my colleagues recommended two other options:
- Book Depository UK: good prices, free international shipping, fast delivery, but at first glance less books than Amazon
- Booko book price comparison: compares multiple sites including Amazon and BookDepository. Presumably make money using affiliate links from search.
I'll be giving these a go and posting on the experience in future.
