Price change is not fundamental to economics. It is fundamental to a post-Fed inflationary policy that seeks for a low (or at least a consistent) unemployment rate. That being said I think this is a great case study of "menu costs" on steriods.
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.
