It's been possible to buy the book from amazon.co.uk for a while but we've only just added links to amazon directly from our site. Although we prefer you to buy direct from us (while our online shop is still open) or from our preferred retailers (see the book FAQ for details), Amazon often discount heavily so it's worth checking their current prices.
If you want to buy from amazon, please use any of the links that are now in the corner of every page, because Exploding Pen benefits from the referral fees.
