I can't speak for the rest of the country, but I live on the Isle of Wight which is only 26 miles wide. Despite this we have (had) a Jessop's store and two branches of a family run photographic business (which also sell hi-fi equipment).

I'm sure that if our tiny island can support two independent shops, then there are other similar businesses in the rest of the country. Perhaps they can now do oven better without Jessop's there as the obvious first place for a customer to try.
