There are lots of shortages all caused by Brexit hold ups. I don't shop in shops any more but on a regular weekly basis when I do my online shopping I see items that are not available, and when I look at amazon for imported items such as cat food of a particular brand, I see that what I could get next day delivery or in a couple of days is very much on the back-burner with delays of 3-4 weeks. It depends what you buy - if it's all local then things are OK, but as soon as you look for something that has to arrive from outside the UK there are delays - however, the Brexiteers among us will never admit this.
