Stores: Remove WH Smith UK

Searches return 0 results.
On inspection eBooks no longer appear to be sold by WH Smith.

Instead product pages for books on WH Smith contain text such as
"Also available on eBook for £xx.xx. Click here to purchase from Rakuten Kobo"
with a deep link to the relevant kobo.com product page.

Additionally the landing page of Kobo on WH Smith also just links to Kobo.com.

As such it seems wise to delist this store.
