Sherry Vinegar 4 Years Aged 375ml – 2x 375ml

This might be a price glitch, but Amazon have honoured them before.
Under normal circumstances, a single bottle is £8.99, with a twin pack at £13.99. But if you read the description, at 3 points it mentions it is a 2 bottle pack. Thus the headline price of £4.50
But if you really use this vinegar, then go for the 2 litre at £13.88 for 2 litres
