Well, they are hardly cheap to buy! Which I didn't mind when they were great. Imho, the only ones consistent and good are the Chilli ones, no variation since introduced. The others, espec. Cheese and Onion are utter rubbish, Rammell as my dear departed Mum used to say! Every now and again I relent and try them and they are worse than Golden Wonder and that's saying something ( the only wonder is / was that anyone bought them ). As for the factory, I am certain they are produced in London, as this is the only manufacturer not to reply to my enquiry if they make Sam's crisps. I will do more to establish this as time goes on.
