BookButler

Just found this brilliant meta-search engine for buying books: BookButler.

It searches 70 online bookshops & marketplaces, with both a simple & an advanced search option. Hits are returned in price order & one click takes you through to the relevant page on the seller's site.

According to its copyright declaration, it has existed since 1999, but I hadn't heard of it before. It just got me out of a very sticky situation involving a delayed birthday gift!
