Just a quick post to remind everyone that this weekend is Pentecost weekend also known as Pentecote here in France, so that means besides the shops being shut as per usual on the Sunday, the majority of shops are also closed on Monday as well, check locally as individual stores in different towns may vary.
If the weather is good, which it is forecast to be, then they will probably an increse in traffic as people take short breaks away or make their way to the coast.
