On 24th July 2020, the UK government mandated the wearing of face coverings in all shops in England. I'll not be visiting non-essential shops while this law is in-place, so I'll not be able to give an informed impression of the French bookshops in London at present. Consequently, this guide is withdrawn.

To those who find themselves in a similar position, I'd recommend FNAC who deliver to London rapidly and at reasonable rates.

The guide will return if/when the law is repealed.
