How is this different from saying someone selling a fine bottle of wine for $2 in New York is scamming you, because you could get the same bottle for $2 in France... ?
If we can get good wine at $2 in France, a fine bottle of wine at $2 in NY is still a bargain. But a NY-based company saying they'll revolutionize wine industry by selling quality wine at $2/bottle, might be trying to scam you.
