People with longer memories may recall that WHS used to operate a travel division in the US (which was later sold to Hudsons), but in recent years have re-entered the US travel market.
Also, infamously, is the satirical Twitter account WHS Carpet that has been highlighting the poor state of their UK retail stores (facilities and merchandising) for some years (stores underinvested in terms of refurbs and labour hours to make a good experience for the customer).
Yes WHS has a website to sell books, stationery, but not sure how well that trades vs. Amazon and various other UK bookseller/stationery websites.
