Duty Free Shops
Is there a duty free shopping area at the Grenoble Airport?
Yes, there are at least two duty free shops at the Grenoble Airport. But I'm not sure they are all the much cheaper than buying at a local shop or hypermarkets. In general I haven't found duty free shops to be much cheaper than French local shops like any of the following - Auchan, Carrefour, Intermarche, Leclerc, Champion and Cora. If you will be driving try looking for a Centre Commercial - shopping centre.
