So after being on this diet for a number of years I decided to start recording the price of oranges.
I buy them by the case at a local wholesaler.
I average approximately 10 cases per month.
But this varies depending on the quality of the oranges and the availability of other fruits (mmm, mangoes!).
So out of general interest I decided to post a graph of the prices over the past year.

The most interesting part is the huge increase in price between September and December of last year.
This was due to the very bad weather that occured in Florida.
Here's hoping it doesn't happen again!
