Query: Old Wessex Porridge Oats

The oats are delicious, and the best I've tasted. I have been ordering it by the case for at least 6 months, and am pleased with the delivery service. What I don't understand is why the product price was increased by almost $10. That seems to be quite steep, and it is a disappointment to see that Amazon has chosen to do this.
