There’s an interesting thing about food in America. I was expecting food to be quite a bit cheaper here than in the UK. Instead, the prices are essentially the same, but you end up getting an incredible amount more, maybe double the portions in the UK. So this means you end up with the somewhat unusual and sometimes unsatisfactory result of not saving any money, but just eating more (or perhaps leaving more uneaten food).
Of course, consumer goods and electronics are still a lot cheaper over here.
