Finder’s Christmas lunch prices 2022: Methodology

How we dived into the cost of Christmas past – and found a number of festive foods to be on par with 2015.

To source the data for this article, I scoured dozens of old Woolworths and Coles catalogues (available online) from 2015 onward. I tracked the regular price for each Christmas lunch item that was consistently available from year to year.

Most items were standard in brand and size. However, I did have to make some assumptions and equivalences which are described below.
