I'm not sure this is the big gotcha you think it is. To serve a large population in a big relatively small area, you can easily achieve your goals with fewer, larger locations. This will allow a greater selection per location, which reduces the odds you will have to wait for the desired product to be shipped in. Moreover, land isn't cheap in New York, whereas it may well be in smaller locales in England. Either way, a reasonable metric is cost per capita to provide services for a region, and England is only about 2/3 as expensive as New York. I suspect the cost of living is higher in New York than England, and it will certainly have an impact of the relative budgets of the two organizations. And we haven't talked about the climate control requirements in England vs. New York because, frankly, I'm not too clear about the relative climate differences to say whether that's a significant issue in the first place.
