What's in your basket ?

I've blogged about this before, and it's always an interesting cultural change.
In order to calculate the consumer price index a basket of goods is selected that represents what many people are currently buying in large quantities. This means that the items change to reflect what people are currently purchasing, and reflects cultural trends as a result. 
For example, streaming music services have replaced other ways of buying music, and similarly various foods wax and wane in popularity over time.

This year, e-cigarettes were in... and sat navs were out for example.

Would be a nice starter activity - what was in and what was out this year...

Office for National Statistics released a useful infographic, which shows some of the changes over the years.

And a more historical one:
