"...will this make Amazon's prices non-competitive"

Amazon UK book prices are mostly full-price outside of the bestseller lists. It's been like this for a while (but it wasn't of course how Amazon started). So you could argue their prices are already non-competitive for many books. It doesn't seems to matter though since all their rivals (who undercut Amazon book prices) are on Amazon marketplace anyway, so Amazon still gets a cut of the sale. Win-win for Amazon.

If you are in the UK, wordery.com is often a cheaper alternative than Amazon for many books. So is bookdepository.com, which is ironic given that it is owned by Amazon.
