Last Sunday, we went to church in Ferney-Voltaire, just over the border in France. We arrived 15 minutes early so went to check out the Carrefour as it was open on Sunday!!

Also, we saw this :
For those reading this blog regularly, you will laugh as just a week ago, I had a post about how I almost cried over toothpicks This is an entire end cap dedicated to toothpicks, in the mixer aisle.

Good to know that the Carrefour in Ferney is opened on Sunday.. I thought everything is closed on Sunday!
Hi Lady J – there are 2 Carrefours in Ferney. The big one (i think) is closed, but there is a little one just 2-3 minutes from that one that is open 9-1 I believe. I got the info/address from their site. Happy French shopping!
The Coop Pronto (very small Coop but with good assortiment) is open 7or 9 – 22h every day, there are two in Genève. In Petit-Saconnex and Carouge.Normally, Coop Pronto is present in train station or gas station but in Genève, there is no one in Cornavin perhaps after the renovation.
