£1 a bottle! Not the highest %alcohol by a long way but a good deal HOWEVER it won't be dispatched for a 1-2 months
BUT used with £10off£50 voucher (SAVETENBWS), it is a great deal if you can wait. Equivalent of 80p a bottle.
Not sure if there's a delivery charge for non-prime.
Full credit to OP Chugalug for the voucher code
