Commercial real-estate. When your store cost at least 10k or even more in rent. You have to sell awfully many deodorants to cover it. And labour isn't exactly cheap either if you want to get some.
That's a good explanation of general price differences between an expensive and a cheaper area, e.g. that Manhattan prices would be 50% higher than more rural New York prices. But I was under the impression here that deodorants in particular were 2-3x more expensive on manhattan, but that the difference was smaller for other goods.
Usually the US (Even the most expensive parts) would be a lot cheaper than e.g. Oslo or Zurich. That's not the case unless there is something else going on here , e.g. that they aren't the same product due to different size and so on.
