I have 12 miniature bottles of 3 star courvoisier brandy bought 1990's and found in loft, they are unopened and in a rather grubby gift box. Can I sell them and where and how much can I realistically get for them. As a pensioner the cash would be useful. They cost £4.51 when purchased.
I do not think the alcohol sales would apply to a small private sale like that.
If you have a small 'corner shop' with a licence near you I would ask the owner if he is interested in buying them. I think miniatures are about £2 each now to buy new.
12 miniatures wouldn't even add up to a bottle. As Chrissa says, either drink them yourself, or, if that is not to your taste, donate them to a charity bazaar. Either way, you'll get a warm feeling.
