Hard to say. There are a lot of products that depend on climate, resources and so on. You can't have same price of oranges everywhere, f.e..

Pork is occasional match, really Russia a colder country, so growing a pig needs more energy. But energy is cheaper here, and that make price equal. Retailing pork does not depend on climate, but depend on fuel price, shop land price/taxes/rent and so on. So retailing here is cheaper.

Also currency rates, stock market games and so on.

However it could be interesting to convert prices into something fixed and independent, like total energy units needed to create product and compare.
