Looking on ebay, if you varied your soda purchases to avoid flooding the market, you could likely sell them for far more as collectibles.

[yes, I realise that wasn't the point - I just find it fascinating how much people are paying for old soda cans]

That's way above the US inflation figures for food and beverages ($17k), and less even than US medical ($22k)

The pound inflated a little more on average, to £18k, but nowhere near that 95p inflation.

Coca-Cola is an outlier as it was affected by the sugar tax, and I’ve used post tax figures.

Now do housing and healthcare.

I did do healthcare - $10k becomes $22k. Housing $10k becomes $17k (rent is a little higher at $20k but housing in general brings it down)

That rent figure is based on "Raw Consumer Price Index data from U.S. Bureau of Labor Statistics for Rent of primary residence"

Clearly that can vary by city/state
