The Paris-Lyon-Marseille axis
If prices are cheaper than the national average on the entire western side of the country, the Gironde is an exception to the rule. In 34th position, prices are 0.5% higher than the French average. On the contrary, the Vendée, the least expensive French department according to the study, displays prices 4.8% lower than the national value. According to Emmanuel Cannes, price and inflation expert at NielsenIQ quoted by Franceinfo, this phenomenon is explained by “historic basins of stores which have rather an aggressive policy” on prices.
In New Aquitaine, prices are 3% lower than the national average in Charente-Maritime, 2.1% in Dordogne, 1.9% in Charente, 1.7% in Landes, 1.1% in Lot -et-Garonne and 0.9% in Pyrénées-Atlantiques.
