The shop woody suggested is nearer to your hotel,but sounds like it might not have a lot of stock at all times.
The one I mentioned is a dedicated Tabac,packed floor to ceiling with the evil weed,and just a smattering of bottles and confectionary.
If you go down to the centre of the village,walk past the little harbour (don't blink) continue on this road,slightly uphill a couple of hundred yards the Tabac is on your left.
If you find yourself in a 'simpsons' type bar you have just passed it.
Good luck..
