What does stuff cost in France?

You’re from the US, aren’t you? Look out for dollar-euro exchange rates. Right at the moment, the US-dollar is very weak compared to the euro. Means you can’t buy a lot of euros for your dollars. As you still have half a year to go, you should get a website where you can watch the exchange rates. And buy euros when the dollar is strong. Prices are usually quite stable in France. So if the dollar gets stronger compared to the Euro you can buy a lot more goods for the same amount of dollars.

Expect that food will be generally more expensive than in the US. Except wine. You can buy very good wines for low prices in France. And yes, the French consider wine food. You can buy it in the supermarkets.

Gasoline will be extremely expensive in all countries of Europe. We pay extreme amounts of save-the-environment-energy-taxes.

As to taxes: they are always included in the prices that you see in shops.

European cloth sizes are measured and labeled differently. So are shoe sizes. Try everything on until you have an idea of the size system.
