I was in St Omer (northern France) last Saturday, and when buying in the
market, they (consistently) priced with a resolution of 1c and totalled
the bill precisely, but then only charged me the price rounded down to a
5c multiple. So for example, item A was weighed and labelled as 1.28
euro, item B was labelled at 1.59 euro, the total was 2.87 euro and they
gave 15c change from 3 euro.

I imagine they would accept 1c and 2c coins, but I didn't try.

The strange thing about France is that several years after going over to
the Euro, many bills and credit card slips still have the amount in
francs as well as euros. I am not sure why this is.
