My local casino had a promotion where you could win these playing blackjack. I have 5 bottles of Gran Patron and 5 bottles of Cles des Ducs XO Armagnac available.
Gran Patron 700ml - £190
Cles des Ducs - £65
Have beat the lowest price I could see anywhere online
Will offer a discount on a bulk purchase
