The Ortis and Dom Littlewood head-to-head challenge to find a budget TV did not name a specific website to search for the best deal. Ortis used a phone app called Barcode Scanner to check for the lowest price of a specific 37" model he liked the look of being sold by a major electrical retailer. He checked for reviews on sites such as Amazon.co.uk, TechRadar.com and AVforums.com but any product price search sites remained unnamed.
