For example olive oil seems to have gone up a lot.
In November we paid £1.89 for a 750 ml bottle of Extra Virgin Olive at Aldi. (£2.52 per litre)
In early December the price was £2.09 (£2.78 per litre)
The same 750 ml bottle today (11th Jan 2019) was £2.19. (£2.92 per litre)
That seems to be (approx) 16% increase in just three months.
By way of comparison, a 5 litre can from our local wholesaler was £9.99. (£1.99 per litre) Also Extra Virgin - not light olive oil.
Value of the pound going down as the cost of imports is going up I guess.
