7Dayshop's prices seem to have become progressively less competitive over the last few years. Although they're still selling 4x5" colour film at significant discount against UK pricing. e.g. Ag photographic - 23.95 GBP inc VAT for 4x5" 10sh Provia 100F. 7dayshop 14.90 GBP max 4x5" 10sh Provia 100F . Robert White sell for between Ag and 7dayshop but charge for shipping, so Robert White would be less expensive for a large order of film.
