It's been a bit hit and miss here for a couple of weeks, I have two main supermarkets within walking distance and some things I just haven't been able to buy. Items in short supply that I've noticed are some salad and veg items, particularly tomatoes, oils (you can't buy rapeseed in our area, so people are turning to vegetable and olive if no sunflower), Tescos canned tomatoes, tissues, mayonnaise and the cat food my boys like was low yesterday (had a few times in last two years it hasn't been available though).
I had to substitute something for a planned meal the other day and it didn't quite work and there are going to be more times like this, but if that's the worst of my problems, compared to what the poor people in Ukraine are going through and people here struggling to feed themselves.
With regards to how much oil people use, I'm a mini prepper so tend to one one or a few in hand of things, so I have 1.75 bottles of sunflower oil last sell by date Feb 2022 - I don't need any more as I wouldn't use it in time. I have a friend who frys in water (her food is yummy though) - not quite sure how she does it without burning, but she copes so I need to find out more!!
I read something about there been a lorry drivers strike, I think in Spain, that could be affecting some fresh veg.
