Like in any country, prices for food items will vary between cities. A little market in central Paris will charge much more for a liter of milk than a large grocery store outside of the city center. In our comparison we're using the prices of our recent trips to our local store- a larger chain grocery store called Carrefour. The US prices are based on recent ads we found online, personal experience, and some other online resources.
We've converted the Euros to Dollars for an even comparison. As of today the USD is at the highest rate of 2014 against the Euro. 1 USD = .78 Euros. A few months ago 1 USD would only get you .74 Euro cents.
