I think people are prepared to pay for stuff when there is a clear difference. With produce that is a lot easier to be different than something that you can buy online. Sometimes it makes no sense at all, there is a place I pass once in a while that does amazing homemade scotch eggs. Some have chilli, some have black pudding in the meat some plain. I went past this week, thought I'd get a couple for lunch. Two scotch eggs and a can of coke cost £9.60, they were lovely but I could have got a meal,pudding and a pint in Whetherspoons for that
