Sweet offer.
Having said that, is it even worth going over to France at the moment for booze given the exchange rate? (Genuine question, I have no idea what sort of savings you'd make).
I go every two months.
On average a bottle of wine at Tesco's in England for say £5.00 can be purchased in France for about £3.00 at Tescos France.
You can still buy cheap plonk for about £1.50 a bottle.
