We buy our dog food in 12kg bags every couple of months and I've just placed an order with our ususal, very competitive supplier with their usual free delivery.
This time around the bag is £54.06, in June it was £47, March £46.35, December '20 £45.09. That's nearly £9 more, a 20% increase in under a year. Prior to that it had been in the mid £40 range for the previous 3 or 4 years.
