At a high altitude, the gravitational force is slightly less than at a low altitude, which means the weight (force due to gravity) of the gold will be less at a high altitude for the same mass. If the supplier buys gold by weight (which depends on gravity) at a high altitude and sells it by weight at a lower altitude (where gravity is slightly stronger), the gold will weigh more, thus making a profit since the price is per newton (a unit of force).
