Au contraire - price change is a fundamental aspect of economics. Why would a new competitor selling the same commodity ever expect to be successful? Because they've figured out how to provide the same product for less expense. So even ignoring expected price decreases due to technological progress, we'd still expect to see prices occasionally decreasing due to organizational progress.
Not to contradict, but to add detail: land, labor, capital, material resources and market seldom exist in the same location for any specific good/service, and the cost of distance (and the cost to overcome those distances) affects market bearable prices. It need not be technological progress that makes one competitive, it may just simply be favorable proximity to resources and markets that gives you an edge.
Coca-Cola (the syrup) is produced IIRC in only one place, and bottled/canned with local waters in regional centers because the cost of shipping a product that is mostly water around the country/world will drive costs up.
Many auto-makers in the US became "competitive" by closing factories where labor costs were high and opening them where they were lower. Many foreign producers of cars opened factories in the US to offset the increases of labor costs in their own countries while also decreasing shipping costs (especially for Asian car makers who cannot as easily ship to the Eastern US) and nullifying punitive tariffs.
