A new Tescos was built here recently, a Tescos Extra, massive store. But they only send film out to be processed. Also recently one branch of Boots in Worthing has stopped selling film (one still sells it) which was a bit of a shock. I think now in Worthing (pop 100,000) there is only one place to get film processed, Jessops as I am not sure if Boots still do it, and I don't use them as I just want the negs which they won't do without scans or prints.
Looking like home C41 might become more economical!
